Sorry Lourry, my post was very brief & not too explicit.
Now() alone, will format it as you requested, automatically.
You don't need the Format() function. ...just for the record... But obviously, it still works. & good to know in general.
topgeek, you can use the DateDiff() function.
it takes 3 obligatory arguments.
DateDiff("m",date1,date2)
1st argument returns the type of value you want returned.
How many months "m" separate the 2 dates, or how many seconds "s", or days "d".
The 2nd argument is, usually, the earlier of the dates (start time), 3rd argument the later date. If reversed, you'll get a negative return.
Good luck to both!
