What this tool does
This converter handles lengths of time, not points in time: use it for "how long", not "when". Because calendar months and years vary in length, the month here is defined as 30 days and the year as 365 days, which is the convention used for durations. If you need an exact number of calendar days between two dates, use the date difference calculator instead.
