Years to Weeks
A year is approximately 365.24 days, the time Earth takes to orbit the Sun once. A week is 7 days, a unit with no astronomical basis but used worldwide for scheduling and calendars. 1 yr equals 52.1775 wk, 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
wk = yr × 52.1775
yr = wk × ≈0.0191653
Worked example: 5 yr × 52.1775 = ≈260.888 wk.
