A more thorough explanation:

A DIE DATUS

A lease provision establishing the beginning of the rental period. The term comes from the Latin phrase "given from (such-and-such) a day."

1. The lease agreement stated that the tenant's occupancy would begin on August 1st, a die datus.

2. The landlord and tenant agreed that the rental period would start on the first day of the month, a die datus.

A die datus is a term used in lease agreements to specify the exact date when the rental period begins. This provision is important because it determines when the tenant is responsible for paying rent and when they can move into the property. The examples illustrate how a die datus can be used in lease agreements to establish the start of the rental period.
