How many days and nights in a week?

Answer 1

There are seven days and seven nights.

Half of the seven nights will start at 12:00:01 am on Sunday, the first day of the week. Six more nights will be observed. Then on Saturday, with six and a half nights having took place so far, the last half night will start, then end at midnight.

Then a new week starts.
