RE: Iranian Calendar
Hello, I am slow these days to answer, sorry for that; I'm getting over the exams now. I read the mailings for the last few days about the calendar. It's nice to see new and knowledgeable friends like Hooman Mehr and Ordak D. Coward taking part here. There were things new for me and mixed up a bit. Let me brief out what I understand out of the mess about the solar calendar. Please correct me wherever I'm wrong. The calendar Hejrie Shamsi comes in types: - The early solar calendar (Hejrie Shamsie Borji), an observational solar calendar with tropical years. The months are synchronized observationally with the duration sun stays in each of the 12 zodiacal constellations, which vary between 29 to 32 days for each month with an accumulation of 365 or sometimes 366 days a year. - The old Jalali calendar, a true solar calendar with twelve 30-day months followed by 5 or 6 additional days at the end to fill a complete solar year. It starts with 'Norooze Jalali' [*]. - The modern Jalali calendar in use in Iran (Iranian calendar), reworked on the old Jalali calendar and uses the same leap structure; consists of six 31-day plus six 30-day months followed by a month of 29 days or 30 during a leap year. It starts with 'Norooze Jalali'. - The afghan Jalali calendar. It has the same month lengths as the Iranian calendar but the leap years are synchronized with the concurrent Gregorian years. Afghans celebrate Norooze Jalali but the first day of the year might start with an offset of 1 day from the Iranian calendar. [*] Norooze Jalali: The first day of a Jalali year. It is defined by the 'Tahvil' moment, the exact tick that the center of sun passes the point of vernal equinox in the northern hemisphere of the earth. If Tahvil happens before noon of the meridian of Tehran, then Norooz is the same day otherwise Norooz is the next day. There are different methods to estimate the precise moment of VE. The effort is to find the one that is as much as possible close to the real occurrence of the phenomenon.

It also does not work based on a specific region. It simply lets you adjust it manually by 2 days. It means it has always a probability of 1 or 2 days of error and seems that they prefer this descripency in return of the other advantages it gives: to cover every variant and every region, and the ability to fix the calendar in case that the observations change the authoritative estimated version of the calendar at any time. It is possible to implement the Hijri calendar the way ODC suggested, using online tables of Hijri adjustments for the past years but it still limits the divices to be online and yet it's impossible again to find assured correct dates in the future. With the current conditions in mind I think it is not out of sence to choose this particular calendar for the OS to be ordinarily useable rather than tailoring it for complex calendarical conversions.

Re: Iranian Calendar (P.S.)
Hi Ordak, What you say makes perfect sense. I just didn't want to go into detail of everything in this regard. Suffice it so say, in such cases people come to agreement on establishing such authorities as part of their civil society. I vaguely hinted this in my post. Such an authority develops out of the needs of daily social life and as a normal (say democratic) civil authority and not a dictated sacred authority which could abuse its power by taking calendar hostage. Note that it gets very tricky for a religion to define and establish something. There is endless potential for abuse. People tend to put a sacred halo around it, and you know what happens next... So, the calendar authority is needed but religion is not in the right entity to establish it. When a religion needs to rely on a calendar, it needs to establish it in a way that the algorithm is very simple and accessible for ordinary people and ensure that it leaves the origin of the authority (or decision) with people so that they can delegate their right as they see fit. The fact that Iranian authorities in this regard act as if they are directly appointed by God is another story... Hooman On May 19, 2004, at 3:04 AM, Ordak D. Coward wrote: Dear Hooman, I am not trying to be annoyingly responsive, it is just a bad habit!

For example, if a contract between A and B requires A delivering a product to B at a certain date, then the two entities would need to choose an authority to resolve their confict in case of B's claim that A did not deliver on time. -- ODC On Tue, 18 May 2004 20:48:09 +0430, Hooman Mehr [EMAIL PROTECTED] wrote: On May 18, 2004, at 2:48 AM, C Bobroff wrote: On Mon, 17 May 2004, Hooman Mehr wrote: P.S.: Although Hijri calendar (and definition of the prayer times) look very strange and primitive, there is a very good philosophical reason behind it which makes sense once you know it.

The calendar authority is people, it comes from individual people with their personal observation, interpretation and judgment. Everybody can verify claims made by others. People usually voluntarily delegate this observation to a trustworthy group in a civil society. On the other hand, they may collaborate to ease the observation and get reassurance and support of others, while still keeping the final decision to themselves. This concept is closely related to some modern day concepts like human rights, diversity, democracy and freedom of information.

Hi Ordak, Lemme welcome you to our list. Comments below. On Tue, 18 May 2004, Ordak D. Coward wrote: - As the lunar calendar in Iran is observation based, there is no way to have an exact conversion for a date in future to/from lunar calendar. However, it is possible to do so for past dates. What I suggest is that the implementation SHALL convert dates precisely for past dates, and do a best guess conversion for future dates. Hence, the conversion algorithm (or a related resource) needs to be updated at most 12 times a year, and in case of Iran, only at the beginning of Ramadhan and Shawwal. This update could as well be propagated through a network protocol like NTP (Network Time Protocol). Also, the conversion shall try to conform to the official published Iranian calendar for future dates in the same year. For future years, it should calculate the lunar calendar using astronomical methods. That has been our (FarsiWeb's) idea too. BTW, the protocol better be XML-RPC over HTTP. - Mordad vs. Amordad. I have seen both in calendars, but I guess I do not count, as I have been out of Iran for a long time now! Anyway, I have only seen Amordad in day planners marketed at the higher end. So, in my opinion, Mordad or Amordad are both fine. Although I prefer to see Mordad myself. But, I think this should be a user option. And does not need to be implemented at the convesion level Omid is working on. I still vote for Mordad. Using Amordad is like writing Ordi-Behesht instead of Ordibehesh. The fact is that, languages change over time. It's like using Shaksepearean English. - b.z vs. asr. I do not know the flexibility of the API, but it would be nice if we can have three designators, sobh, asr and shab. sobh is for 6:00 am to 11:59pm. asr for 12:00 am to 5:59pm, and shab for 6:00pm to 5:59am. The time ranges are not exact, but they are close to what you hear if you want to set appointments in Iran. Exactly. In fact I have proposed this one: 00:00-00:59: Nimeh-shab 01:00-06:59: Bamdad 07:00-11:59: Sobh 12:00-12:59: Zohr 13:00-18:59: Asr 19:00-23:59: Shab - Jalali vs Iranian. I strongly prefer Jalali, as it refers to a spcific method of keeping dates regardless of the country it is used in. For example, if were still under Qajar rule or Pahlavi rule, then we would have either used Hijri-Qamari calendar or Shahanshai, still both would have been considered Iranian calendar. So, in a country which has recently changed its official calendar a few times, we better stick to a name that will be in place regardless of the government. I am under the impression that the current calendar is use is techincally Birashk's calendar. Birashk perfected the old Jalali Calendar (which had 33/128 year periods vs 33/128/2820 year periods of Birashk). I'm still against Jalali, because as Roozbeh mentioned, the Jalali calendar has been different in number of months. To be exact, we should call it Birashk, but since it's highly unprobable that the Iranian calendar changes again, I say lets stick with Iranian Calendar. About Shahanshahi era, a good converter can assume years 2500-2600 are in this era (Hint Hamed). - Birashk's book. He had published a book on his work, if memory serves me, it was called 'taarikh-tatbighi-ye Iran'. He had a few examples of different date conversions, using a rather large table for lookups. That table could be used as a test vector for the date conversion utility. I once did my own derivations to derive his table, and except one entry, my code and his table conformed. I never figured the source of the discrepancy. I just ordered the book. Will let people know when I get my hands to it. -- ODC PS. I hope no one gets offended by my chouce of pseudonym.

I went back and read most of the Iranica's entry on calendars. It seems to me that the correct name of the current calendar in Iran is Hijri Shamsi, and NOT Jalali calendar, so I take back the suggestion of Jalali. As the first day of year in H.S. calendar is Norooz-e-Jalali, then a common misconception is that H.S and Jalali are the same. Norooz-e-Jalali refers to the method of detrmining the first day of the year -- the day sun enters Aries. Iranica also mentions a 128 year period for calculating leap years, which I think is the same method Omid is using is his implementation. I guess the 33 year period is attributed to Khayyam. And, 2820 year period to Birashk. Now, I have no idea which calendar the Iranian government uses. I also found the link: http://www.angelfire.com/dc2/calendrics/ which I find interesting and amusing to read. Essentially the author argues that the 33 year period of leap years is more precise than the 2820 year period.

Re: Iranian Calendar
Hi Omid and Connie, MSDN way of specifying Hijri calendar is like saying the length of any month in Gregorian calendar is 30 days plus or minus two days -- true but not very useful. Alright my example is grossly exaggerated, but I mean to highlight my point. The official Iranian Islamic Calendar is computed by a body called Showraa-ye Aalie-e Taghvim (quoting Roozbeh's spelling). It comes up with an initial estimate (or best guess) of the *adjusted* calendar which is usually only re-adjusted for Ramadan. This pre-adjusted calendar is not the same as the basic table in MSDN, nor the mostly observational Hijri calendar meant by MSDN and common in Saudi Arabia. You can verify my assertion by looking at the published calendars for the past few years and see that it does not match perfectly. To be honest, the last time I checked was more than 10 years ago and I no longer have the specifics, so I'll be glad to see it verified again to see if there is any changes in how that mysterious chamber calculates it. On the other hand, you can come up with good research work in academia around the world in this regard (like the link Omid mentions), but none of them will be the official Iranian Islamic Calendar even if it matches the past history of the printed calendars perfectly. This is the same funny (or sad) issue already raised for 2820-year Birashk calendar. As a result, I am against treating this calendar to be the same as Hijri calendar with MSDN definition or any none official academic definition, even if the difference would be one day in 50 years. Algorithmic calculation of a pre-adjusted Hijri calendar is potentially way more complicated than Birashk calendar and is always less precise, so there is more potential for variation among the different bodies calculating it. It is affected by exact geographic coordinates (not just time-zone), height of the location, neighboring ground texture (being water, mountains, etc.), relative position of sun and earth or in common terms season (seasons in the Hijri calendar rotate, so that the same month is sometimes in mid-summer and sometimes in mid-winter) and atmospheric visibility, which is a momentary condition and impossible to calculate, only possible to statistically estimate. And I am not even beginning to talk about the human observer as another key factor... If we want to strictly adhere to its true (religious) definition, even the best guess will be meaningless without actual observation. In Saudi this is the case with their religious Hijri calendar, they may adjust each month based on official[see endnote] observation. Note: Observation along with some rules (to cover bad weather) define this calendar not calculation. This is not the case in Iran where the best guess of the mentioned official body (regardless of the algorithm they are using) is considered good enough except for Ramadan where again we have the definition based on official observation. Please note that a good calendar software service in an operating system or application should be able to tell you precisely what was the date say 100,000 days ago at a specific location (within the range of validity of the calendar, of course) or what date it estimates to be at a specific location 100,000 days in the future. Naturally, the more confident the future estimate the better, but some calendar systems simply don't permit this by their very definition. I don't know the approach taken by the contractors for the calendar project in FarsiLinux, can someone comment on this?

Re: Iranian Calendar
Hi, Thank you for the refinements and clarifications. Maybe I've used to the old Mac OS calendar API which used to correctly support dates way before Gregorian calendar existed (even before Christian era). On the other hand, even if you reduce my suggested number to 2000 days, you'll find differences and it won't be unreasonable to expect an OS to support it.

Unfortunately, I don't have access to them at the moment, maybe later. ok, the info is online at Encyclopaedia Iranica: http://www.iranica.com/articlenavigation/index.html search under calendars--Islamic period page 672 (you can't seem to go there directly as they have a pdf file for each page) Here's the relevant part: On 24 Esfand 1354 Sh. / 14 March 1975 the Majles approved a new era based on the supposed year of accession of the first Achaemenid king, Cyrus the Great (559 B.C.); thus, 21 March 1976 became the first day (Nowruz) of the year 2535 in the Shaahanshaahi era. The month names of the Persian solar Hejri calendar were retained wihout change. Official documents and publications were dated according to the new calendar. This caused much confusion and created widespread discontent, particularly among the clergy. Eventually, on 5 Shahrivar 1357 Sh./27 August 1978, the government, in the face of the coming revolution, reverted to the solar Hejri calendar. This calendar is reckoned from 1 Farvardin, 119 days before 1 Moharram of the Arabian lunar year in which the hejra took place. The Julian date corresonding to the first day of the solar Hejri era is 19 March 622. Taqizadeh gives 17 March 622 (1937-39, p. 916), which was apparently the date arrived at by the Persian commission for calendar reform in 1304 Sh./1925. Wow, 3 whole years it lasted! However, must have been a productive 3 years as I do come across publications with the Shahanshahi date now and then. I still think it's worth mention in your documentation.

Re: Iranian Calendar
Hi Behdad, I have a question (targeting you and everybody else working on Persian locale projects such as .Net) The lunar Hijri calendar used in Iran is also an official calendar and is calculated independent from other Hijri calendars used in other islamic countries. It is an important calendar, since it determines half of the holidays on our calendar. We also know that it has slightly different month lengths than other Hijri calendars. Are you going to identify and support that calendar as well? Then what would you call it in English? The answer to this question may affect Iranian Calendar term as well. If you ask me, we can keep Iranian Calendar and call the Hijri calendar Iranian Secondary Calendar or Iranian Religious Calendar or something like that. I think we should avoid solar / lunar designations in the English name to make it more meaningful and less confusing for none-Iranians. With the same logic one may suggest using Iranian Primary Calendar instead of Iranian Calendar to emphasize the fact that more than one official regional calendar exists in Iran. My final verdict?

Re: Iranian Calendar
Hi Hooman, Thanks for the question. I go with Iranian Islamic Calendar. I think Primary/Secondary and Solar/Lunar are both very bad names. And Islamic makes sense since that's what this calendar is called in English, so ours is the *Iranian* Islamic Calendar.
