World-clock comparisons can cross midnight. A city may be several hours ahead or behind and can therefore show yesterday or tomorrow relative to you.
How to use this information
- Compare the full local date as well as the time.
- Open city details to confirm the selected time zone.
- Account for daylight-saving changes when planning a future call.
Important details
- The displayed offset can change seasonally for regions that observe daylight saving time.
- Two cities do not necessarily change clocks on the same date.
- Time-zone rules are determined by regional policy and system data.
Practical tips
- Include the date in international invitations.
- Recheck recurring meetings around seasonal clock changes.
