Since there are 12 months in a year, we can calculate that there are approximately 4.33 weeks in each month (52 weeks divided by 12 months).

Calculating Weeks in a Summer Season

To calculate the number of weeks in summer, we need to consider different methods based on how summer is defined.

It ends with the autumnal equinox, typically on September 22nd or 23rd. Astronomical summer encompasses about 13 to 14 weeks, depending on the exact dates of these celestial events.
