Is the rent due between the first and third dates of the month?

There is actually a new management company and I think the rent is due on the 1st, no grace period. That's how it was with the previous management company. A few years in the past the management company at that time would allow you to pay within the first couple of days without any penalty but now I operate as if it's due on the 1st with no grace period, and if it's on the second it's going to be considered late.
