Reason: 1, 8, 15, 22, and 29 all fall on the same day of the week (for example, Monday).
And after the 29th, there are 30th and 3rd1.
Because July 1 day has five weeks, 3 1 must be on Sunday at the latest, that is, the 29th can start from Monday and be on Friday at the latest.
Attachment: Students, you can make a list. If 1 is a week, then the 8th,15th, 22nd and 29th are all Mondays and five weeks. So I think Monday to Friday is fine.
