How does the Date Calculator handle leap years?

The calculator uses JavaScript Date objects which automatically adjust for leap years (e.g. adding 1 year to February 28, 2024 results in February 28, 2025).

Can I add weeks and days together?

Yes! The offsets are accumulated. Entering 1 week and 3 days is treated as adding or subtracting a total of 10 days.
