Date Conversion Utility GUI

A GUI utility to compute calendar date, GPS time, Julian day, and day of the week

You are now following this Submission

This GUI will allow you to quickly and easily compute the GPS time and week number (modulo 1024) of a given (Gregorian) calendar date. It will also allow you to do the reverse operation of computing the calendar date, given the GPS time.

Both calculations will display the Julian day and the day of the week.

The screen shot shows the results of computing GPS time at the GPS birth date (midnight of January 5, 1980)
