If the rent starts the same day under either version, there may not be financial issue unless there are deadlines that start with the execution of the lease. If you are signing on a day other than what is indicated on the contract, insert as of before the date. That is a shorthand message that you actually signed it on another day, but that you wish the contract to become effective on the indicated date.
