Conversion from Year (yr) to Month (mo) and vice versa
Updated on by Stefan BanseHere you can convert the Unit of time Year into the unit Month and vice versa you can convert Month into Year. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., yr to mo or mo to yr. With the following calculator you can also calculate any other Unit of time.
Info about "Year"
A year (a) (Latin: annus) forms the time span of 365, or in the case of a leap year, 366 consecutive days. Due to its varying length, the year is not a physical unit of time and thus not a unit of time in the international SI system of units.
In the time unit converter, a year is always calculated with 365 days.
In astronomical terms, a year is defined as the duration of the Earth's orbit around the Sun, which lasts 365.25 days on average. Due to the a quarter of a day more than 365 days, a normal calendar year (common year) is defined as 365 days, which is replaced every four years by a leap year with 366 days.
In everyday life, the term "year" is understood to mean the period from 1 January to 31 December.
Info about "Month"
A month forms the time span of 28, 29, 30 or 31 consecutive days. Due to its varying length, the month is not a physical unit of time and thus not a unit of time in the international SI system of units.
To enable a general conversion, e.g. into seconds, minutes or years, the average length of the month in days is is defined: Since a year consists of 12 months, a normal calendar year with 365 days results in a month length of 365 / 12 = 30,416667 days
In astronomical terms, a month is defined as the period of one complete revolution of the moon. Depending on the definition, the lunar month averages a little more than 28 days.
