Approx. 52 weeks in a year, thus 13 weeks in 3 months. select numberofweeks/13*3 as numberofmonths from yourtable or if you want whole months returned select floor(numberofweeks/13*3) as numberofmonths from yourtable
>>> Allan Kamau <[EMAIL PROTECTED]> 2008-05-30 11:21 >>> Hi all, I have a simple question (tried googling but found no answers). How do I convert weeks elapsed into months elapsed? I have data that contains duration in weeks (without any other date values such as year and so on) for example a week value of 14 and I would like to convert the 14 weeks to 3 months (some lose of accuracy expected). Expected tests may be: 14 weeks yields 3 months. 1 weeks yields 0 months. Is there such a function. The rudimentary solution (may reduce lose of accuracy) am thinking of is to add the weeks to the value returned by clock_timestamp() then subtract clock_timestamp() from it. The question now is how to convert the returned value to months elapsed as opposed to days elapsed.
