Hotel Pre-opening calendar

Hi everyone,
Whiat do you think, in your experiences, would be the ideal advance period to start preparing the opening of a new property? Like marketing, hhrr plan, preparing purchase system, etc. Less than 50 rooms.

Thank you all

@MartaCabrillo2020 should have a good pre-opening checklist to track all the required to do task per department no matter how small or big your hotel are.
