Purpose
Day of work and exceptions displaying on wrong day of week
Approach
We have some problem in react-big-calendar with timezone (Moves everything over a day) more details in
jquense/react-big-calendar#118 ,
jquense/react-big-calendar#809 and etc.
How you can see for timezone 0 and bigger work correctly (Screenshot section). Current bug reproducible only for timezone less than 0. This is problem with "react-big-calendar" all the days shifts over by 1 and this is workaround for resolve problem with "react-big-calendar". For resolve current problem we use accessor and offset hours.
