Answer 2

Explanation:

1. February is the second month of the year in the Julian and Gregorian calendars, with 28 days in common years and 29 days in leap years.
2. The duration of day and night differs through the year because of the axis of the Earth. The Earth is tilted at an angle of 23.4°. Owing to this reason, the daylight is higher in summers than that in winters, and hence the difference in the duration of days and nights.
