Montreal to IST
Montreal is 9 hours and 30 minutes behind India Standard Time.
Times may vary due to daylight saving time.Quick answer. IST is 10 hours and 30 minutes ahead of Montreal for part of the year and 9 hours and 30 minutes ahead for the rest, because Montreal observes daylight saving time and the other side does not. The gap is 10 hours and 30 minutes during Montreal's standard-time months and 9 hours and 30 minutes during daylight time, so always convert against a specific date.

Business hours and meeting times
Comparing a 9:00–18:00 working day in Montreal against 9:00–17:00 in IST, across the whole week — a slot only counts if it lands on a working day at both ends.
Both sides work Monday to Friday, so the working weeks line up and you share 5 days.
Rows are days in Montreal. Columns are hours of the Montreal day.
No standard overlap
A 9–6 day in Montreal never meets a 9–5 day in IST on any day of the week, so one side has to move outside normal hours. Ranked by how far outside:
- 9 AM Montreal = 6:30 PM IST — well outside normal hours — 2 hours and 30 minutes beyond
- 10 AM Montreal = 7:30 PM IST — well outside normal hours — 3 hours and 30 minutes beyond
- 11 AM Montreal = 8:30 PM IST — well outside normal hours — 4 hours and 30 minutes beyond
These hold on every shared working day (5 a week). Teams working this gap regularly tend to alternate which side takes the early or late call, and keep the synchronous meeting short.
Public holidays
A shared working day is only usable if neither side is on holiday — and India and IST build their calendars on different systems, so the days each loses rarely coincide.
Over the next 8 weeks you share 40 working days. 4are lost to a public holiday on one side or the other, leaving 36.

India has three national holidays on which the whole country closes. Everything else is either a central-government gazetted holiday that individual employers choose to observe, or a state holiday. Festival dates follow lunisolar calendars and move every year, so they are listed explicitly rather than derived.
Holiday dates for Montreal and elsewhere come from a dataset last refreshed on 2026-09-12 (date.nager.at plus curated national calendars). Lunar dates — Eid, Chinese New Year, the Jewish holidays — are predicted and can move by a day once officially announced. Regional, state and employer-specific holidays are not included.

Frequently asked questions
What is the time difference between Montreal and IST?
It depends on the date. IST is 10 hours and 30 minutes ahead of Montreal in January and 9 hours and 30 minutes ahead in July, because Montreal changes clocks for daylight saving time. Use the converter above with the date you actually need.
What time is 9 AM Montreal in IST?
9:00 AM Montreal is 7:30 PM in IST during IST, and 6:30 PM during daylight time. The table on this page lists all 24 hours for the date you pick.
What is the best time for a meeting between Montreal and IST?
Standard working days do not overlap at all in this pair, so somebody has to stretch. The closest slot is 9 AM Montreal / 6:30 PM IST — it well outside normal hours — 2 hours and 30 minutes beyond. Teams that meet regularly across this gap usually alternate who takes the awkward end.
Does Montreal observe daylight saving time?
Yes. Montreal alternates between EST (UTC-5:00) and EDT (UTC-4:00). In 2026, clocks in Montreal go forward on March 8, 2026 and back on November 1, 2026. India does not shift at all, so the gap between the two moves twice a year.
When do the clocks change in Montreal?
In 2026, clocks in Montreal go forward on March 8, 2026 and back on November 1, 2026. Between those dates the gap from India is 9 hours and 30 minutes; outside them it is 10 hours and 30 minutes.
Why does the Montreal–IST difference change during the year?
Because Montreal switches between EST (UTC-5:00) and EDT (UTC-4:00) for daylight saving, while the other side does not move. A converter that assumes one fixed gap will be an hour wrong for roughly half the year.
How many hours a week do Montreal and IST actually overlap?
None at standard hours. A 9–6 day in Montreal does not meet a 9–5 day in IST on any day of the week, so a recurring call means one side works early or late — the section above ranks the least disruptive options.
Do public holidays in Montreal and IST line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 4 of those are a public holiday on one side or the other, leaving 36. The next holiday in IST is Gandhi Jayanti on 2026-10-02. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is Montreal ahead of IST?
No, it is the other way around: IST is ahead of Montreal by 9 hours and 30 minutes to 10 hours and 30 minutes.
