Unit definitions

What is a month?

For duration conversion the month is treated as an average of 30.4375 days (365.25 ÷ 12), since calendar months vary from 28 to 31 days. This average is suitable for rough estimates such as loan terms or subscription lengths, not exact calendar arithmetic. Use a date calculator for precise month differences.

What is a year?

For duration conversion the year is treated as the Julian year of 365.25 days, which averages in the leap day. It is close to the actual mean calendar year and suitable for interest, age, and long-span estimates. For exact dates, use a calendar-aware date calculator.
