Ruben Q L commented on CALCITE-5113:
------------------------------------

[~itxiangkui], if I understand your description, you are saying that MySql returns 0 for {{week(date '2022-01-01')}}, but Calcite returns 52?
If that is the case, I'd say that Calcite result is correct, according to how week 1 is computed (https://en.wikipedia.org/wiki/Week#Numbering)
