UX: daily automatic grouping for less than 34 days instead of 30 (PR #13437)

GitHub

Why 34 and not 31, 32 or 33?

Because it can go from start of month 1 to end of day of first day of month 2. which technically is 32. As we dont really care if it’s exactly correct, I put extra safety. We just want to avoid weekly for a month and daily for a lot.
