"There are four weeks in a month."

Translation: एक महीने में चार हफ़्ते होते हैं।

[pravinthsam]

Do we need to add होते before the end? I chose महीने में चार हफ़्ते हैं।

[jetsconnor]

Not a native speaker, but in another thread someone explained that होता is used when making a statement that is more... defining, I guess, and not merely a matter of current circumstance. The sky is blue, apples are a type of fruit and a month has four weeks.

[Udbav1]

Death, taxes, four weeks in a month.

[ErwinRooij]

Habitual. The way it is.

[skorab88]

What is wrong with saying एक महीना?

[ErwinRooij]

It's not in the oblique case. Month is the object, not the subject, so it becomes महीने instead of महीना.

[Beth205297]

I thought महीने was plural and महीना singular? Why is the plural used here?

[enidl2]

महीना becomes महीने because it is in oblique case when using the postposition में .
In this sentence it is not plural.

[NikhilJohn12]

Why is it Mahine and not Mahina?
