Lease termination notice

[Zakaria Haque]

Hi Everyone,

I sent a 90 days notice to one of my tenants starting from 11/09/20-02/10/21.But now i now i feel like she is not goona move by then so i contacted a lawyer and he said the notice that i sent is not valid beacuse 90 days has to start from the beginning of the month.He said the judge would deny the notice beacuse it was incorrect.Is it true that i would have to give 3 full months instead of 90 days? beacuse everywhere i read it says 90 days not 3months that equals to 90days.Please help

FYI-The tenant has been living in there for 3 years and NY requires 90 days.Also, I need to get done some work in the property and i cant do it until it’s vacant.
