Google Calendar treats timed events as specific moments and displays them in each viewer’s local time zone. All-day events work differently: they use calendar dates, not appointment times. That distinction—and the event’s time-zone settings—explains why an event can show different clock times to people in different places.
Timed events are moments; all-day events are dates
A timed event has a start and end date-time. In the Calendar API these are start.dateTime and end.dateTime. An all-day event instead uses start.date and end.date. Both endpoints must use the same kind of value: a timed event cannot have one timed endpoint and one date-only endpoint. Google’s API documentation says the time-zone field has no significance for an all-day event. See Google’s event and calendar concepts and the Events API reference.

For all-day events, the API’s end date is exclusive. For example, a start date of May 16 and an end date of May 17 means the event covers May 16 only. This convention lets the end value mark the boundary after the event’s final date.

Google says event times are converted to UTC and shown in each viewer’s local time zone: “When events are created, they’re converted into UTC, but you’ll always see them in your local time.” (Google Calendar Help: Use Google Calendar in different time zones.) As a result, a meeting can appear at one clock hour for its creator and another for an attendee abroad while still representing the same moment.

The time zone attached to an event provides context for its scheduled time; the viewer’s local zone determines how that moment appears on their calendar. Calendar also adjusts its display when users travel. Different displayed clock times do not, by themselves, mean that invitees have different event start instants.
How an event’s time zone affects its start and end
Calendar lets you assign a time zone to an event. In the API, a timed date-time can include an explicit UTC offset, be paired with an IANA time-zone identifier such as Europe/Zurich, or use UTC. A date-time must include an offset unless a time-zone field is supplied. These supported forms describe the event’s time; a named zone additionally records the zone context.

Events that start and end in different zones
A single event can have different start and end zones. This is useful when an event, such as a journey, begins in one zone and finishes in another. In Google Calendar on a computer, open the event editor, select the time-zone control beside the event time, choose the relevant zone, and save. If the start and end are in different zones, select Use separate start and end time zones. The control is described in Google’s time-zone Help page.
Recurring events use one zone
A recurring event needs one time zone so Calendar can expand its occurrences consistently. The series’ named zone matters when the intention is for an event to recur at the same local wall-clock time as the seasons change; that is different from scheduling a fixed UTC instant. For a recurring event, the API’s top-level start and end describe the first occurrence.

Daylight-saving and time-zone rule changes
Google warns that events in past or future years may not always reflect daylight-saving changes correctly. It says displayed times adjust automatically as dates move within a few years, but a region’s rule change may affect an event created before Google knew about that change. If an event appears at an unexpected hour, check its event zone and the current rules for that location. Google’s qualification is on its time-zone Help page; it is not a guarantee that every historical or far-future event will display as intended.

- Event zone: The zone associated with a timed event. A single event may use distinct start and end zones; a recurring event requires one zone for recurrence expansion.
- Calendar zone: The calendar’s default zone, which can affect how event retrieval results are interpreted or displayed.
- Requested response zone: A
timeZoneparameter can request API response times in a zone; otherwise, the calendar’s zone is used by default.
The calendar zone also determines the bounds used when matching all-day events in time-bracketed queries. For the Events: list method, the timeMin and timeMax filter bounds must be RFC3339 date-times with offsets, and the documented bounds are exclusive. These query boundaries are separate from the event API’s start-inclusive, end-exclusive convention.

Quick Recap
Quick diagnosis when a time looks wrong
- If attendees see different clock hours, compare their local time zones; the event may still refer to the same moment.
- If the event should use a particular location’s clock, check the event’s time-zone setting rather than relying only on the viewer’s zone.
- If an event crosses zones, verify whether separate start and end time zones are appropriate.
- If it is all-day, confirm it is stored as dates rather than timed values, and account for the exclusive end date when using the API.
- If the event is recurring or far in the past or future, consider whether daylight-saving or local time-zone rule changes affect the displayed hour.
