Is it common in English to say 'Thursday nights' instead of on Thursday nights'?

[tulipflower]

I saw this sentence in a film. 'We have a regular game Thursday nights, just some friends I went to school with'.

Is it common in English to omit the preposition 'on' in this situation?

 

[tedmc]

Yes, it is getting common to omit the preposition before the day of the week.

 

[emsr2d2]

I think it's always been quite common in AmE. It's not very common in BrE and I haven't noticed it becoming more so.

 

[Charlie Bernstein]

It sounds totally natural to the American ear.

 

[Tdol]

It's not very common in BrE and I haven't noticed it becoming more so.

But not unnatural.

 

[jutfrank]

I'd say it's fairly common in British English.
