Q: There is no Europe/Minsk timezone in iCloud calendar interface. All scheduled events are displayed with 1 hour error.

Hello there, Kirik17.

The following Knowledge Base article reviews how to make the changes to your Time Zone on iCloud.com:

Thanks for reaching out to Apple Support Communities.

Hello again, Kirik17.

I was able to test it on my System and was able to locate your Time Zone.

One thing to keep in mind is that the the map may not snap to your unique city, but may be a major Metropolis/Capital in the vicinity of Minsk.

For me it helped to click just above the area that corresponds to the Black Sea and Sea of Azov. That snapped the city to Kiev, Ukraine. If you snap a little higher than that it will jump to Helsinki, Finland. Either of these cities fall within the "Eastern European Time Zone which,  as you say, are GMT +2.

Hoping this helps you adjust your setting as desired.

Cheers,

Pedro.

Hello again, Kirik17.

The concept still holds true. When clicking to select your time zone, you will need to select another city within your same Time Zone so that that one becomes your default.

If you are still unable to select your Time Zone, you may find more information by using another one of Apple's Support Resources at: https://getsupport.apple.com/GetproductgroupList.action.

Cheers,

Pedro.
