Never used this one.

Never used these either.

IME, it's by far the most complete and most versatile Date module.  
Unfortunately, it has one drawback - it's SLOW.

Interface is easy to get used to.  I wrote an extension to Date::Calc for 
handling holiday data obtained from a database (instead of files), plus 
handling other things we needed.  I evaluated Date::Calc, Date::Manip, and 
at least one other (can't remember) and went with Date::Calc because we 
needed the speed (it's MUCH faster than Date::Manip).

Looked at it some.  I haven't used it as it didn't fit anything I needed 
any better than Date::Calc.

Yep.  Date::Calendar::Profiles is very nice as well (but missing alot of 
data).  By the way, does anybody know of a programmatic way of calculating 
the equinoxes and/or chinese new year?

Haven't used.

Nice for what it does.

Haven't used any of the other specific ones Dave listed.
