Also, the termination date must be the last day of a rental period. For example, if tenant pays rent on the first of each month, the termination date must be the last day of the month. If the tenancy is for a fixed term (for example, a lease for one year), the termination date cannot be earlier than the last date of the fixed term. Exception: The termination date must be at least 28 days after the landlord gives tenant this notice if his/her tenancy is daily or weekly.
