The same conversion works for every city on these clocks, such as India to New York, India to Toronto and Delhi to New York.
Shaded areas follow the official zone boundaries, so a country split across zones is split here too. Hover or tap a region for its local time.
Every hour of Tuesday, October 27, 2026, side by side. Days with a clock change show 23 or 25 rows.
Shaded rows fall inside working hours in both places.

India Standard Time is UTC+5:30 all year. The whole country keeps a single clock, and India has not observed daylight saving time since the 1940s, so IST never changes.
IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
Eastern Time follows the clock in New York. It is Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) from the second Sunday in March to the first Sunday in November.
People often write EST all year round. Strictly, EST is only the winter offset; in summer the eastern US is on EDT. The converter follows the real New York clock for the date you pick.
EDT is 9 hours 30 minutes behind IST for most of the year (238 days in 2026). The gap is 10 hours 30 minutes for about 18 weeks in 2026.
New York uses Eastern Time. EDT is 9 hours 30 minutes behind IST for most of the year (238 days in 2026). The gap is 10 hours 30 minutes for about 18 weeks in 2026. Type any IST time into the IST to EST converter to see the New York time for any date.
9:00 AM IST is 11:30 PM (previous day) EDT for most of the year (238 days in 2026). 9:00 AM IST is 10:30 PM (previous day) EST for about 18 weeks in 2026.
12:00 PM IST is 2:30 AM EDT for most of the year (238 days in 2026). 12:00 PM IST is 1:30 AM EST for about 18 weeks in 2026.
10:00 AM IST is 12:30 AM EDT for most of the year (238 days in 2026). 10:00 AM IST is 11:30 PM (previous day) EST for about 18 weeks in 2026.
