TIME ZONE FIELD NOTES
EST, EDT and IST:
which time do you mean?
One hour can change a meeting. Use the date and the intended Eastern rule, not the abbreviation alone.
The short answer
| Time zone | UTC offset | India is ahead by |
|---|---|---|
| EST · Eastern Standard Time | −05:00 | 10 h 30 min |
| EDT · Eastern Daylight Time | −04:00 | 9 h 30 min |
| IST · India Standard Time | +05:30 | — |
Here, IST always means India Standard Time. The same abbreviation is used for other time zones elsewhere, so write “India” in an invitation.
For a New York meeting, choose New York
New York follows Eastern Standard Time in winter and Eastern Daylight Time during daylight saving. If someone schedules a call for noon in New York, its India time depends on the date.
- January 15, 2026 at 12:00 in New York → 22:30 in India.
- July 15, 2026 at 12:00 in New York → 21:30 in India.
- 12:00 at a fixed UTC−05:00 offset → 22:30 in India, on either date.
If an invitation says “EST” in July, that wording alone does not establish the organizer’s intent. Confirm whether they mean fixed UTC−05:00 or local Eastern time.

March 8: a missing hour
At 02:00, New York clocks move forward to 03:00. A local time of 02:30 does not exist that day. Choose a valid time before 02:00 or at/after 03:00; the converter will not silently move your meeting.
November 1: a repeated hour
At 02:00 daylight time, clocks move back to 01:00 standard time. New York 01:30 happens twice:
- First occurrence: 01:30 EDT → 11:00 IST.
- Second occurrence: 01:30 EST → 12:00 IST.
Choose the occurrence explicitly before copying or sharing the result. Converting from India gives a unique moment and includes the Eastern offset.
Crossing midnight changes the date
January 15 at 20:00 fixed EST becomes January 16 at 06:30 IST. In reverse, January 15 at 08:00 IST becomes January 14 at 21:30 fixed EST. Always copy the date as well as the time.
Agree a window, then share one dated time
There is no single meeting time that suits every team. First ask each person for their available hours and the meeting length. If both sides only accept 09:00–17:00 locally, there is no overlap between New York and India on either example date below.
Example assumptions, not your team’s working hours: New York accepts 09:00–17:00, and the person in India has explicitly agreed to a later 10:00–20:00 window. Use New York local time (America/New_York), so its Eastern offset follows the date. These are single-date examples, not an automatic availability check.
| New York date and overlap | India date and overlap | Time available |
|---|---|---|
| January 15, 2026 09:00–09:30 EST UTC−05:00 | January 15, 2026 19:30–20:00 IST UTC+05:30 | 30 minutes Convert winter start → |
| July 15, 2026 09:00–10:30 EDT UTC−04:00 | July 15, 2026 18:30–20:00 IST UTC+05:30 | 90 minutes Convert summer start → |
The entire meeting must fit: under these assumptions, a 30-minute winter call can run from 09:00 to 09:30 in New York and 19:30 to 20:00 in India. A 60-minute call does not fit that winter overlap. If either person cannot accept the example hours, agree different hours; do not treat this table as their availability.
For a 10 AM New York example on July 15, 2026, 10:00 EDT (UTC−04:00) is 19:30 IST (UTC+05:30) on July 15. At 10:00 in New York on January 15, the clock uses EST and India is already at 20:30 on January 15, outside the assumed India window.
- Open a dated example above, or start with India time. Enter the date at the starting location and select New York local time for a New York meeting. Use Fixed EST only if the organizer explicitly means UTC−05:00 year-round.
- Check both dates, the EST/EDT label and UTC offsets. Convert the end time too, using its actual date if the meeting crosses midnight. For a recurring call, check each meeting date around clock changes; this tool does not create a recurring schedule.
- Select Copy result and paste the dated result into your invitation. Include the duration or the separately checked end time. A copied start time alone is not the full meeting slot.
- Select Copy share link, reopen it and check the date, direction and rule before sending. Anyone with the link can read those settings. The link does not book a meeting, check calendars or confirm attendance.
