About time units
The second is the SI base unit of time, defined by the vibration frequency of the caesium-133 atom. Minutes, hours and days build up from it in fixed steps (60, 60, 24). Weeks are exactly seven days, but months and years vary in length, so this converter uses average values: 30.44 days per month and 365.25 days per year.
For exact calendar spans between two specific dates — including leap years — use the date difference calculator instead.
