I bet your code does not even address one of the technical issues I mentioned: the number of days in February depends on the year, and your scenario (to the small amount it was revealed) postulates that the year is selected _after_ selecting month and day. But I do accept the idea that you can make almost everything work in 4 lines of code in JavaScript. You might just need extraordinarily long lines at times. -- Yucca, http://www.cs.tut.fi/~jkorpela/

I also have that routine and it does account for 28/29 days in February even the case where the 400 year century is not a leap, not that I really care about in my case... Your are correct on February if the client selects the NEXT year ddand it happens to be a leap year. February 29th will not appear in the drop down list. Also, I did find my earlier post. Sorry folks for the double post.. I doubt it will happen again. Bruce
