While I cannot give you legal advice in this forum, as a general matter you have to pay the entire month. However, remember, if he demands you pay the full month, then you do not have to give him the keys until the last day and he cannot re-rent until after the 30 days expires. So you do have some negotiating power to ask him to waive some of the rent. If you come to an agreement, do it in writing and make sure to get your security deposit back.

landlord can apply security deposit to rent for days you wre there unpaid. I would rather have him do that then hope he refunds rent afterwards.
technically though you have to give 30 days notice as well so you're not really entitled to leave early. not paying the full month could theoretically create liability.
practically speaking, though, the security deposit is probably going to be your only dispute after you move out
Responses to Avvo questions are based on a general discussion of the law and in no way constitute legal advice. No attorney-client relationship is created, and you should not take or fail to take actions based on my answers. Consult an attorney in your area. Time is often of the essence. Act quickly!
You owe him the full month's rent on the first. If you move out early, you are still liable for rent for the rest of the month.
But your landlord may be thrilled if you move out earlier. Ask him if you can only pay, for example, three day's rent and, in return, you will be out in three days. You may of course agree on any time you want. I am just using three days as an example.
You are much better off discussing this with him now rather than moving out and then saying he owes you rent (which he won't).
