OOo starts dating at 30/12/1899 but shows in a cell as Dec 29, 1899 when MMM DD, YYYY formatting is applied. It appears to lose a day. The 30/12/1899 date none-the-less is the date that is used for internal date arithmetic, is it not? In Help the WEEKS() Function is defined as follows: WEEKS(Start date, End date, Type) Calculates the difference in weeks between two dates. Start date: First date End date: Second date Type: Calculates the type of difference. The possible values are 0 (interval) and 1 (in numbers of weeks). If the Start date is set to 30/12/1899 and End date is today, WEEKS() returns 5562 weeks for Type value 0 and 5563 for Type value 1 -- a 1 week difference. 'Help' is not clear on the difference between interval type (0) and 'in number of weeks' type (1). I assume Type 0, simply means the net date value is divided by 7, while Type 1 is an actual count of weeks. What I really want to do is count the number of Mondays since the 30/12/1899 start date. I think this means I should use Type 1 but I would like to have that assumption confirmed, if someone could take the time to help. -- Regards Bill --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
