Q:

where does the apostrophe go in this sentence?

Where would the apostrophe go in:
'he dedicated his days to...'
Would it be days, day's or days'?
Thank you.

A:

Your first option is correct, there is no apostrophe.
The possessive in this sentence is in 'his' which does not require an apostrophe, and 'days' is a simple plural.
