Conversion Definitions
Months: A month is a unit of time based on the roughly 30 or 31 days it takes for the Moon to orbit Earth. There are 12 months in a calendar year, each varying slightly in length, commonly used to organize the yearly cycle of seasons and events.
Years: A year is a time period representing the duration Earth takes to orbit the Sun once, about 365.25 days. Years are divided into months and days, serving as standard measurement for age, time intervals, and calendar cycles.
Conversion FAQs
Why do we divide months by 12 to get years?
