Which time zones are considered most comfortable for remote or international work?

For remote or international work, comfortable time zones are those that allow overlap of working hours between teams in different regions. Usually, these are:

• UTC±0…+3 — European time zones, convenient for collaboration with Europe and Russia.
• UTC-5…-8 — US and Canada time zones, if the team is in America.
• UTC+5…+9 — for teams in Asia and Russia.

It is optimal to choose time zones with overlapping working hours (for example, 9:00–18:00) so that synchronous meetings can be held and information exchanged quickly.

For flexible work, time zones with a difference of no more than 3–4 hours between key participants are often chosen. For example, if the team is in Moscow (UTC+3) and Berlin (UTC+1), a 2-hour difference is convenient.

If the work is fully asynchronous, the time zone is less critical, but it is still important to consider employees' rest and sleep times.
