Frequently asked questions
- What happens when adding months pushes past month end?
- JavaScript's Date handles month overflow automatically: adding 1 month to January 31 gives March 2 or 3, since February does not have 31 days.
- Can I subtract time by using negative values?
- Yes — enter negative numbers for years, months, or days to subtract instead of add.
