If the date is 30 December 2007 ($unixdate=1198965600) Not accordingly to my calculations -- try it: http://webbytedd.com/c/unix-time/ Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com -- The standard date calculations don't show a week number. If you use 1198965600 as the decimal seconds in your form you'll see that the human date is 30 December 2007 12:00:00. But if you try date(W, 1198965600) you'll get a value of 01 for the week number. This conforms to the ISO date standards, but it doesn't help much when you're trying to calculate the real week number. Luckily (?) this year is a bit of a fluke or I might not have detected this error in my script - the next time it happens is in 2012. I fixed it by taking the long code route: use the week number for December 28 yyyy if the date is > December 28 yyyy, check for a sunday between December 28 and the date and increment the week number. I now get week 53 for 30 December 2007. Cheers Arno
