Suggestions for a date picker that supports mm/yyyy

Does anyone have some suggestions for a date picker that supports
mm/yyyy.

Also, does anyone know the "best" way to validate a mm/yyyy as "valid"?
Meaning this month or the future?

Thanks,
Jason

Do you mean a GUI component?

Test the entered month and year to see if they are >= the present month and
year? You cold do this by adding the present year * 12 to the present
month, this gives you an easily compared integer with units of months. Do
the same to the user's entry and there you are.

If you include days and require the resolution of days, things become more
complicated, but for the case of month and year, it is rather easy.

Not sure exactly what validation you are doing with month and year. Maybe
you mean mm/dd/yyyy?

But, FYI, you can probably validate dates without too much effort
since there are only 14 calendars.

One for Jan 1 on each day of the week, and another similar seven calendars,
except that the year is a leap year.

Leap years are yyyy % 4 == 0. This tells you which of the two calendars to
choose, assuming you know what day Jan 1 falls on.

To get that, pick a starting point and see that Jan 1 moves forward one day
for each year, and two days for the year following a leap year.
