dd8a67f4f9e5e8930457203c18205183b8306b5a by Abseil Team <absl-team@google.com>:

Change the suggestions for the non-strict Next/PrevWeekday() calls.

Previously we suggested `PrevWeekday(d, Weekday::thursday) + 7`
to get the _following_ Thursday if d is not already a Thursday,
but `NextWeekday(d - 1, Weekday::thursday)` is more intuitive,
and probably even a little faster.

Similarly for the _previous_ Thursday if d is not already a
Thursday, suggest `PrevWeekday(d + 1, Weekday::thursday)`
instead of `NextWeekday(d, Weekday::thursday) - 7`.
