Ask a math expert, if you work for seven years and take a year off, how many days off on average?
Leap year: 366 days

Average year: 365 days

Work for 7 years and take a year off. According to the leap of 4 years, it is ***8 years, so there are two possibilities:

(1) Leap years are all work, that is, rest in normal years.

Work: 366×2+365×5=2557 days.

Rest: 365 days

(2) A leap year is work and a leap year is rest.

Work: 366× 1+365×6=2556 days.

Rest: 366 days

This is just the answer to the question given by LZ. If it is a real problem, it is necessary to remove the statutory rest days and adjust them according to different regional policies.
