I appreciate all the info on this thread. Appears entry is fairly simple and getting back to normal. I do have a question about the 24 hour covid test to get back to the USA . ( I know it is one of the more ignorant policies left , but short of going to Mexico and crossing the border it is still required )

I have 1225 am flight. I presume my test has to be done the calander day before which is in effect the same day ? I will be staying at the Intercontinental in Bangkok. Is there a good testing site that can get one done in a few hours ? Thanks
