When is this tool useful?
- Calculate a deadline by adding a number of days to today's date.

How does the calculation work?
The calculator adds or subtracts the entered duration from the chosen date. Months with different lengths (28 to 31 days) and leap years are automatically taken into account by the PHP date engine, so the result is always accurate.
Good to know
You can combine years, months, weeks and days in a single calculation. Leave fields at 0 to ignore them. The result shows the exact resulting date and the total number of days between the start and the result.
