Married and engaged ladies

When did you send out your save the dates? My wedding isnt until july 10th 2020 but it is on a friday and an hour and 15 minutes out of the city. I dont have any guests super far away that im inviting. My wedding is in the evening as well to prevent people from having to take time off of work. Due to it being an hour and 15 out of the city, some will probably opt to get a hotel room which will need to be booked in advance. How many months before the wedding should i send out my save the dates?
