Start with the organizer's announcement
A webinar, class or community session usually has a fixed start. The useful question is where that announced moment falls in your day. Compare the organizer's city and your own before deciding whether you can attend the whole session.
An ET label needs a date to resolve the applicable offset. Confirm that the organizer means New York's timezone and check whether a weekly series keeps the same host local hour. A copied conversion from last week's session can become misleading.
Give the event a clear place in Time
- Set your profile's own timezone to the city where you expect to attend. The app's date exploration uses this reference for local inputs.
- Add the course provider as an organization or the venue as a place, and select the organizer's confirmed city timezone.
- Use a recognizable event name or group so several courses remain easy to distinguish. Save only manually verified hours that are useful for comparison.
- Read the announcement for the full host date, start and expected length. Ask the organizer to clarify missing timezone information before converting it.
Try a fictional webinar announcement
This fictional webinar starts on 2 November 2026 at 18:00 in New York. London is the other city in the example. Read each card's calendar date and offset to see how the fixed announcement fits into the attendee's local day.

Check whether the session fits your day
- Open the fixed start with the example's button. For your event, convert an ISO timestamp with an explicit offset or Z, or a Unix timestamp. If only the host's date and clock time are given, first switch the profile's own timezone to the host city, then enter that date and time in date exploration. Keep your own city as a favorite to read the result.
- Check your local date as well as the hour, then manually compare the announced length with your commitments and any preparation you need.
- For a weekly class, select the next occurrence's actual date and compare again. Repeat around clock changes instead of assuming a permanent gap between cities.
- Share a temporary read-only view if another attendee needs the comparison. Explicitly save a dedicated learning profile only when you want to reuse its favorites.
Separate the time comparison from attendance
The meeting tool matches manually chosen hour ranges and duration. For a fixed event, an inconvenient local result is a reason to ask the organizer about alternatives; moving a comparison does not change the announced start.
Keep the official announcement nearby to check revisions and joining details. Cached profiles can support offline comparisons; optional Google Drive sync helps reuse saved favorites on connected devices.
