[shudder] There are already WAY too many calendar systems. Inventing a new one is probably not such a good plan...

Take a look at the MySQL date ranges -- They may have a data type that allows for more than just 1/1/1970 to 3/??/2038 If not, consider using PostgreSQL which has VERY extensive and flexible date support, for ranges MUCH larger than 0 BC/AD. http://postgresql.org I believe PostgreSQL even supports time scales on the order of geological events and for astronomical purposes, though not with "day" accuracy. I am assuming that by "accurately" you mean "to the nearest day" since you spoke of "exact days", right? But you didn't define how far into the future you need to go. Current time? A few years out? Stardates from Star Trek? You have to specify a start date, end date, and accuracy to choose a correct calendar system. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
