Why does the windows 8 "calendar" confuse the days of the week when synchronizing?

Question

Data synchronization

for a recurring event in the standard "calendar" application in windows 8.1, the option "on Tuesdays and Thursdays" is set;
I open the application on a laptop - the days of the week are the same, but the calendar grid shows on Wednesdays and Fridays
events rise on Tuesday and Thursday only if you select for them other days, and then return "Tuesdays and Thursdays". after which I watch these events on a stationary computer again on Wednesdays and Fridays
, maybe this is the setting for the day of the beginning of the week, which I could not find, maybe someone remembers? or knows the reasons for this behavior
. Thought he got around the problem - made two weekly events on Tue and Thu with the specified start and end dates of the interval. are also shifted to Wed and Fri on a laptop

Answer 1

Probably, different time zones are set on the computer and on the laptop?
