About this converter
Seconds, minutes, hours, days and weeks are exact multiples of one another. Months and years vary in real calendars, so this converter uses the mean Gregorian year of 365.2425 days (and one twelfth of that for a month). The 365.2425 comes from the leap-year rule: a leap day every four years, except in century years not divisible by 400. For exact spans such as a notice period or a loan term, count calendar days instead. The fixed units are simple: a day is 86,400 seconds, a week 604,800 seconds, and an hour 3,600 seconds.
