@tsarstepan,
Our (federal, state & local council) elections all happen on Saturdays, tsar.
So most people can easily attend a polling station - open from around 8 am to 5 pm. (they're all over the place in the city, generally in school halls, church & local halls, etc. It's about a ten minute walk to get to my nearest one.)
Same in the country areas: local halls, schools, etc become polling booths for the day.
Those who can't attend (for legitimate reasons) can arrange to cast an absentee vote beforehand.
It's all pretty easily done, really. No big hassle.
