From February 12, citizens from 80 countries can travel to Belarus up to 5 days without applying for a visa unless you enter and/or exit from Russia. I'm from one of the countries but I wonder how they count the 5 days rule.
Some countries add the arrival date to the calculation; other countries don't.
Suppose that I arrive at 2017-09-01 at Minsk; do I have to leave it on 2017-09-05 or 2017-09-06?
