Using Javascript to format dates

Date masks to try:

• m-d-yy
• d-mmm-yyyy
• mm/dd/yyyy
• d mmmm, yyyy
• mm (mmmm) d yyyy
• m mm mmm mmmm d dd yy yyyy
• are you mad?

Mask format key

• d - day part with no leading zero
• dd - day part with leading zero
• m - month part with no leading zero
• mm - month part with leading zero
• mmm - month abbreviation (e.g. Oct)
• mmmm - month name (e.g October)
• yy - 2-digit year
• yyyy - 4-digit year

Notes

It seems pretty obviousin hindsight that the better way would be to extend the Javascript date object, so that we could just call dateObj.format("dd-mmm-yyyy"). Live and learn--a task for another day.
