So, the key is to find the date of the Vernal Equinox, which as you say, does not always land on March 21. However, every 400 years, it does happen on March 21 7:30am GST. From there, we can derive a base for future dates. Every 4th year is a leap year, and every 4th century, giving 97 leap days each 400 years. so (365*400+97)/400 is 365.2425 gives the length of each year. Then the dates can be calculated as follows: http://phpro.org/examples/Get-Vernal-Equinox.html Any improvements welcomed Kind regards Kevin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
