Frequently asked questions

Can I include a time as well as a date?

Yes, the supported format accepts a date alone or a date followed by a time. If you provide a time, check that it matches the exact moment of your deadline, because the result depends on it.

Why does the result not match what I expected?

First check the date format, then your device time. Mixing up day and month, or using a different time zone, can shift the remaining time shown by the tool.

Does the tool handle working days?

No, it calculates continuous time remaining until the given date. It does not remove weekends, public holidays or breaks. For a working-day plan, adjust the result with your own calendar.
