I am looking for a conventional antonym for peak hour.

As far as I've seen, the term off-peak hours is used. Still, to me this means any hour that is not the peak hour, which is not necessarily the hour with the least clients or activity in a business.

Here is an example sentence:

Eight o'clock till nine o'clock is our peak hour; two o'clock till three o'clock is our _____.

Can anybody please help with this?

  • I'm guessing "slowest hour" is not colorful enough?

Consider slack ("wanting in activity").

Two o'clock till three o'clock is our slack period.


Consider "lull" period which is the slowest time in activities of an establishment.

It's a bit klunky, but I've seen doldrums used this way before:

A state or period of inactivity, stagnation, or slump (Merriam-Webster)

  • What catches me is that M-W calls doldrums a plural noun, yet it's defined as "a state or period". So I'm perplexed whether it would be " two o'clock till three o'clock is\are our doldrums. Apr 19, 2017 at 10:10
