Dude, Terry that's perfect! One of the next projects that I have is to write a Gregorian Calendar!!!

You guys are making me appreciate visual basic a lot more.

yup, and you'll learn to hate that type of stuff. Java takes a very easy task like "what is the date" and makes it really complicated and convoluted.

[bensenvill]

like if it was SQL, the equivalent would be "GETDATE()"

It does what I need it to, and it actually resembles English.
