#### Number of Uses Only Limited By Your Imagination

One user reported he uses the calculator to know when to start his 3D printing jobs, so they are done at the desired date/time (subtracts the 3D print time from date/time he wants it done by).

Want to find out what the date will be when a 30, 60, 90, 120, 180, 365, or 500-day event is set to occur?

Simply select *today* as the starting date, *now* as the starting time, *add* as the operation to perform, and enter the desired number of days to add to the date, and the calculator will tell you the resulting date -- along with the time and day of the week.

Or, do you want to know what the date was a given number of days, weeks, months, or years ago? No problem. Just select today as the starting date, select *subtract* from the operation menu, enter the number of time spans to subtract, and click the "Calculate Date" button!

Here are just a few of the many questions the time date calculator can help you to answer:

- On what day will my 90-day warranty expire?
- On what day is my 60-day note due?
- What day does my 30-day free trial expire?
- What day will it be 100 days from today?
- What day will it be 500 days from now?
- If we met on this date, on what day will our 6-week anniversary fall?
