Convert a webinar time for a support shift

A webinar invite says 10 a.m., but your support team works in another time zone. The difference can change during the year, so a quick mental calculation may put the session outside the shift or on the wrong date.

Compare the cities with the World Clock, then check the event date in a calendar that handles time zones. This helps you confirm the local start time and whether someone will be on duty.

Convert the webinar time

1. Open the World Clock and compare the webinar city with the city where your support shift takes place.
2. Read the event invite carefully. Note the start date, time, and time zone, including whether it says a regional label such as EDT or a UTC offset such as UTC-4.
3. Enter or add the event to your calendar using the organizer's time zone. Check that the calendar shows the event at the right date and time in your own time zone.
4. Compare the converted start and end times with the support shift. Check the date as well as the clock time, especially if the webinar is near midnight in either city.
5. Share the converted time with the team using the city or time zone name, the date, and the local time. For example: July 15, 3:00 p.m. London time.

A world clock is useful for comparing city times now. A webinar is a future event, so use a date-aware calendar for the final conversion. Daylight saving changes can affect the difference between two cities on particular dates.

What the converted time means

The webinar falls inside the support shift

There is likely someone available to answer questions during the session. Confirm whether the shift covers the full webinar or only its start. If questions may continue after the event, allow for a handoff or assign a person to remain available.

The webinar starts before the shift

The team may miss the opening, including instructions or announcements. Ask whether the organizer will share a recording, or arrange for someone on an earlier shift to attend and pass on key details.

The webinar ends after the shift

Plan who will handle questions or follow-up requests that arrive near the end. A short overlap between shifts can help, but do not assume that a teammate is available outside their scheduled hours.

The invite shows different times on two devices

One device may use a different local time zone, or its clock settings may be wrong. Check the event's stated time zone and date before changing the calendar entry. For help reading city times on a shared display, see How to read a world clock board for a team standup.

How to fix a time mismatch

1. Check the event's time zone. Look for a city, a time zone abbreviation, or a UTC offset in the invitation. Do not assume that the abbreviation is unambiguous: the same short label can refer to different places. Confirm the organizer's intended city if it is missing.
2. Check the date, not just the offset today. Daylight saving rules change at different times in different regions. A city comparison that is correct today can be off by an hour on the webinar date. Use the exact event date in your calendar.
3. Set the device's time zone correctly. On Windows 11, open Settings › Time & language › Date & time and check Time zone and Set time automatically. On macOS, open System Settings › General › Date & Time and check the time zone and automatic time settings. On an iPhone, go to Settings › General › Date & Time. On Android, look under Settings › System › Date & time, though the path can vary by device.
4. Reopen the invite after correcting the time zone. Calendar apps usually update local event times when the device's zone changes, but check the displayed date and time. Avoid editing the event's clock time unless the organizer's original zone is clear, or you could shift it twice.
5. Include the zone when you notify the team. State the date, local time, and city or time zone in the message. If staff are spread across locations, include both the webinar time and the support team's local time.

Check the shift handoff

Time conversion tells you when the webinar starts locally, but it does not show whether the right person is scheduled to cover it. Check the roster for the whole event window and identify who will take over if the session crosses a shift boundary. If attendees may submit questions afterward, decide where those requests go and who is responsible for the next response.

Keep the organizer's original time zone in the calendar event so later schedule changes remain tied to the intended local time.
