How to use this conversion for work meetings
Many people write EST when they mean Eastern Time. That can be one hour wrong during summer, because New York uses EDT. For business scheduling, write ET plus the city name, or include the UTC offset.
If this is a one-time call, confirm the exact date before sending the calendar invite. If it is a recurring meeting, check the time again around daylight-saving transition weeks. A one-hour mistake is common when a team uses abbreviations like EST, PST, GMT, or CET without naming the city.
For more than two people, use the Meeting Time Finder. It lets you add each participant, pick working hours, and find the shared window that keeps the meeting inside normal business hours.
