Timesheet projects need to determine the elapsed time between and start and end times, or determine how many hours are overtime.Before you can take advantage of some of the more power date and time formulas, you have to understand how Excel stores dates and times.
don’t ask me why it’s backwards for this type of information…
I don’t have a clue.)Maybe you have data that increases by 5’s or decreases by 2’s…

Regardless of how you have formatted a cell to display a date or time, Excel always internally stores dates And times the same way. For example, the date 19-Jan-2000 is stored as 36,544, since 36,544 days have passed since 1900-Jan-0. It should be noted that the number 0 does not represent 1899-Dec-31. If you use the Actually, this number is one greater than the actual number of days. Excel works this way because it was truly a bug in Lotus 123.
This is because Excel behaves as if the date 1900-Feb-29 existed. The year 1900 was not a leap year (the year 2000 is a leap year). When Excel was introduced, 123 has nearly the entire market for spreadsheet software.
For example, 3PM on 19-Jan-2000 is stored internally as 36544.625.
When you enter a time without a value, such as entering into a cell, the date portion is a zero.
or you could need every 3 days for a period of time…
whatever pattern it is that you need the question is still there.
In Windows98 and Windows2000, you can specify the cutoff year, from the Regional Setting control in the Windows Control Panel.
