Dear Roger, Thank you for your comments on the John Dee implementation of the Omar Khayyam calendar.
> At one longitude, 77° W, the equinox > would always be on the same day. Is this > God's Longitude? Yes. At that longitude the vernal equinox would invariably fall on 21 March. Sadly, this is no longer always the case because U.S. Daylight Saving (did you ever hear my views on that?) now starts on the second Sunday in March, which shifts the local definition of Midnight by one hour, so 1 year in 24 the vernal equinox will be on 22 March. It should be noted that the longitude will depend on where you start the 33-year cycle. John Dee deemed the calendar to start in year 1 [Birth of Christ when zero hadn't been invented] with leap years at multiples of 4 until year 32 and the first cycle concluded at year 33 [Christ's death]. We might note that Omar Khayyam was over 500 years ahead of John Dee and we should also remember Na'amat Allah who was on Pope Gregory's Commission and who almost certainly lobbied for the 33-year calendar. We can represent John Dee's version as: (C C C L)x8 C C = Common Year L = Leap Year We note that 4 x 8 + 1 = 33. There are, of course, 33 points in the cycle which you can deem to be the start point and this will give you other magic longitudes if you are happy not to align your calendar with the life of Christ. > This is relevant today as Donald Trump > is crowned at God's Longitude, 77° W, > Washington DC Someone might remind him of this and, maybe, he can undo the extension of the daylight saving period introduced by George Bush. In this way Trump could reclaim the "line to God" that George Bush carelessly threw away.
