Thank you, but what if the time has elapsed in the original timezone?
For example, let's say in country X the new day begins at 7am on the 30th, but by the time I land in country Y, that day has ended in country X and it's now the 31st, but we're still on the previous day in country Y (30th) astrologically speaking.
Oddly specific I know, but I'm not 100% certain of my travel circumstances and if I'll be able to do the square before leaving for the airport and it'll be a while in between before I find a hotel, and it's a very long flight (12hrs + 4hrs of waiting at the airport, driving etc.)
