I always thought 'what is the working hours?' is correct because we use a singular verb for periods of time.
But, I found the following sentence in a website that confused me again :
The hardest two hours of my life were spent trying to persuade ..., which was found in a website.
So, which one is correct? what is the working hours? or what are the working hours? Is the above sentence simply a mistake?
Please save me from this never-ending grammar confusion. Thanks.
It should be 'are' because 'hours' is in the plural.
