Possible dates for a given day of the week, month, and year

If you know the day of the week, month, and year for something happened or will happen, but you don't know the date, you can use this form to figure out the possibilities. This is for Gregorian calendar dates. This has worked for all the combinations I've tested. But if you find any incorrect results, please let me know. If you don't get any results at all, you may need to adjust your browser to allow it to run JavaScript codes.
