# Is there another calendar with the equivalent of gregorians weeks?

In the gregorian calendar, we split the time in years, months, weeks and days.

A week is the total of seven days.

I was looking at the persan calendar, being one of the most precise known calendar. However, on wikipedia (french page), I cannot find any reference to an "equivalent" of gregorians weeks.

So, is there any other calendar that splits/split months into a unit of measurement we could consider the equivalent of gregorian weeks ?

• It's not clear to me what you mean with "equivalent", may something like this en.wikipedia.org/wiki/Symmetry454? Commented Apr 1, 2022 at 16:25
• The French Republican Calendar, actually used for a time in France... en.wikipedia.org/wiki/French_Republican_calendar The weeks were 10 days each, called "décades". Commented Apr 1, 2022 at 17:51

• While I was more looking for something as Gerald Edgar proposed, your proposition is also a valuable answer to me @user6530. Commented Apr 4, 2022 at 6:17
