AnswerClick to flip back
A
Less than 365 1/4 days
💡 Explanation:
One orbit around the sun (a tropical year) takes approximately 365.2422 days, which is slightly less than 365 1/4 (365.25) days. The difference is why our calendar skips leap years on century years not divisible by 400. The 365 1/4 approximation was used in the Julian calendar but was slightly too long.
