Conversion Definitions

Months: Months are units of time based on the roughly 29.5-day lunar cycle, but in calendars, they vary between 28 to 31 days. The Gregorian calendar divides a year into 12 months which organize the year into manageable parts for civil, religious, and social purposes.

Years: Years measure time based on Earth’s orbit around the Sun, approximately 365.25 days. It is the fundamental unit to represent the passage of time in most calendar systems, used to mark age, historical events, and durations beyond months.
