It makes sense to say, "My working hours are from 9 am to 6 pm."

But is it right to say, "My working hours is from 9 am to 6 pm."

My argument is that from 9 am to 6 pm can be treated as a singular subject, as is "butter and bread".

  • The subject is my working hours.

Since you say 'my working hours', you are referring to each hour in which you work. The fact that they happen to come one after another and form a single stretch of time doesn't necessarily matter grammatically.

You could, for example, say 'my working hours are 9-10 o'clock on Monday, 11-12 o'clock on Tuesday, 9-10 o'clock on Wednesday...' etc and saying 'my working hours' would still be correct because there are multiple hours there, despite they're coming only one at a time.

Were you to use 'is', you would have to say something like 'my shift is from 9-6pm', as the word 'shift' bundles all those working hours into a singular entity, whereas 'working hours' remains plural.


Since you use hours you need 'are' .. You may say: my working time is from 9 am to 6 pm.

  • I agree. And of course, Louis, "My workday lasts from 9 a.m. to 6 p.m." also needs a singular verb...

My shift is from 9 to 6

But shift is a noun in that sentence.
