I have two dates and I'd like to find how many days between these two dates? Ex:
04/03/07 - 03/31/07 should be 4 days!
Thanks

Hi unixgirl,

presently no other clue than to transform the dates: "daysofmonthspassed" + days (easy as long as in the same year, a bit more tricky to reflect leap years and dates covering different years)

sorry for the bad news

Wollie

We've discuss unix date arithmetic a lot in this forum. Take a look at:

Also, take a look William Robertson's excellent shift_date script:

Thanks Nails. I've actually took time to browse thru forum and found one of your response to 'uribo' on get_JD() function. I've used it and it worked on my script.
Thanks again.
