Date Calculator

Find the exact difference between two dates, or add/subtract a number of days, weeks, months, or years from a date.

Frequently Asked Questions

Does this handle leap years correctly?

Yes — it uses standard JavaScript date arithmetic, which correctly accounts for leap years and varying month lengths.

Is this the same as the Nepali (BS) date tools?

No — this works with standard English (Gregorian/AD) dates only. For Bikram Sambat conversions, use the dedicated Nepali BS to AD or AD to BS converters instead.
