Months to Years
A month here is treated as 1/12 of a year (about 30.44 days average), since calendar months vary from 28 to 31 days. A year is approximately 365.24 days, the time Earth takes to orbit the Sun once. 1 mo equals ≈0.0833333 yr, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to time, measured here against time's base unit (s) — every other time unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
yr = mo × ≈0.0833333
mo = yr × 12
Worked example: 5 mo × ≈0.0833333 = ≈0.416667 yr.
