Is there any culture with 7 day a week Mail delivery?

That is, do all cultures have a day where mail carriers do not deliver? In the US and UK this day is Sunday. What about the rest of the world?

Do you get mail on Saturday? I don’t think we get mail on the weekends at all (Canada).

The US gets mail on Saturday.

I was asking, because I was thinking that it would be great to have mail 7 days a week. I didnt think that 6 days a week was ahead of some cultures/nations.

Just out of curiosity, why? Do you still write/receive letters?

My mail is 99% unaddressed bulk mail and bills. I would be happy if Canada Post decided to go down to once or twice a week for residential delivery.

Apparently we used to have Sunday mail in the U.S. in the early 1800s.

If I had to guess a country that might have 7 day a week mail now, I’d gues China, but my google-fu is weak now and I can’t find any mention.

The regular postal service doesn’t deliver on Sundays in Japan, but the larger post offices are open for pickup and sending, and the private delivery companies are also available.
