Is it more correct to say:

Your service expired last June 1, 2017

as opposed to

Your service expired on June 1, 2017

If yes, why?

In this case, I believe that saying

Your service expired on June 1, 2017

would be more correct, since there is no other June 1, 2017, so why would it be necessary to clarify that it was last June 1, 2017?

It would however, be more proper to use last if you omitted the year, or, in other words, you stated:

Your service expired last June 1st.


In this context, last is a relative term -- it describes the most recent event that would fit. For example, one might say I saw him last Tuesday. Here, last indicates that the Tuesday you're referring to is the most recent previous one, not some other Tuesday. If you are using a full date (month, day, and year) then last is not necessary. Your service expired last June would make sense; your example, while not grammatically wrong, is awkward.

On the other hand, on refers to a specific date (identified either by using a full date as you have or by context.) If a full date is not specified, then it is generally assumed to apply to either the most recent or next event. He will arrive on Tuesday would imply the next occurring Tuesday whereas He arrived on Tuesday implies the most recently occurring Tuesday (due to the use of past tense.)

So, to sum up:

Last -- the most recent occurrence, used without a full date
On -- a specific date, identified either by the use of a full date or by context.

I hope this helps.


I think it depends how recently the service actually expired. If in the relatively recent past, say less than six months, then I think "Your service expired on June 1, 2017" is better. "Last June 1, 2017" implies that it was last year, or in the more distant past.
