When does "30 days" begin? (real estate, rent, tenants)

[Katherine]

My landlord mailed a letter of rent increase, and I am trying to figure out how to calculate the prorating I need to do. The date on his letter is March 4, the postmark on the envelope is March 5, and I received it March 7. He is asking for raise to go into effect April 1. I know it's only a few days difference, but I want my reply to him (and my April rent check!) to be fair and correct.
Thank you!

April 7th....

He needs to let you know 30 days in advance, so you can give him 30 days notice if you move. I wonder what would happen if you told him on March 7 that you were leaving at the end of the month? You think he might hold back your deposit to pay for a weeks rent? Yes, I think he would.

With my tenants, I follow the "bankers rule" (completely legal in real estate). Every month is 30 days. You received your notice March 7th. Rents are paid on the first day of the month for that month.

Calculate your rent by the rent amount divided by 30 days. Multiply that amount by 6 days. Then divide your new rent amount by 30 days. Multiply that by 24. That is the amount of rent you owe for April.

Remember, rents are due from the lst of the month to the end of the month. You are not paying for the lst of the month to the first of the next month.

So, you received notice on the 7th. You owe the old amount from the lst to the 6th. New rent is for the remaining 24 days of the month.

Some owners don't apply the "bankers rule". Why he/she didn't get the notice to you sooner is beyond me.........
