Why it takes 365 days between midsummer and the next?

The period between midsummer and the next midsummer is approximately 365 days due to the Earth's orbit around the Sun. The Earth takes about 365.25 days to complete one full orbit, which defines the length of a year. This slight discrepancy leads to the introduction of a leap year every four years to keep our calendar in alignment with the Earth's position relative to the Sun. As a result, the time between consecutive midsummers is effectively one year, or 365 days.
