Question

How many days are there in a non-leap year?

Answer 1

Express number of days in a leap year:

1. The earth takes $365.25$ days to complete $1$ revolution around the sun.
2. Thus, every $4$ years, an extra day is added to keep the calendar synchronized with the seasonal year.
3. This extra day is added to the end of February.
4. Hence, February has $29$ days instead of $28$ days in a leap year.
5. The year having $29$ days in February is called a leap year.
6. So, in non-leap years, there are only $365$ days.

Therefore, there are $365$ days in a non-leap year.
