Business hours and meeting times
Comparing a 9:00–18:00 working day in IST against 9:00–17:00 in Mexico City, 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 IST. Columns are hours of the IST day.
No standard overlap
A 9–6 day in IST never meets a 9–5 day in Mexico City on any day of the week, so one side has to move outside normal hours. Ranked by how far outside:
- 5 PM IST = 5:30 AM Mexico City — well outside normal hours — 3 hours and 30 minutes beyond
- 4 PM IST = 4:30 AM Mexico City — well outside normal hours — 4 hours and 30 minutes beyond
- 3 PM IST = 3:30 AM Mexico City — well outside normal hours — 5 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 Mexico City build their calendars on different systems, so the days each loses rarely coincide.
Over the next 8 weeks you share 40 working days. 3are lost to a public holiday on one side or the other, leaving 37.
| Date | Who is off | Holiday |
|---|---|---|
| Wednesday, September 16, 2026 | Mexico City | Independence Day (Día de la Independencia) |
| Friday, October 2, 2026 | India | Gandhi Jayanti |
| Tuesday, October 20, 2026 | India | Dussehra (Vijayadashami) |

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.

Frequently asked questions
What is the time difference between IST and Mexico City?
Mexico City is 11 hours and 30 minutes behind IST, on every date of the year. Neither side observes daylight saving time.
What time is 9 AM IST in Mexico City?
9:00 AM IST is 9:30 PM the previous day in Mexico City, all year round.
What is the best time for a meeting between IST and Mexico City?
Standard working days do not overlap at all in this pair, so somebody has to stretch. The closest slot is 5 PM IST / 5:30 AM Mexico City — it well outside normal hours — 3 hours and 30 minutes beyond. Teams that meet regularly across this gap usually alternate who takes the awkward end.
Does India observe daylight saving time?
No. India has kept a single UTC+5:30 offset since 1945 and does not use daylight saving time, so IST reads the same on every date of the year. Any change in the gap to Mexico City comes entirely from the other side.
How many hours a week do IST and Mexico City actually overlap?
None at standard hours. A 9–6 day in IST does not meet a 9–5 day in Mexico City 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 IST and Mexico City line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 3 of those are a public holiday on one side or the other, leaving 37. The next holiday in Mexico City is Independence Day (Día de la Independencia) on 2026-09-16. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is IST ahead of Mexico City?
Yes. IST runs ahead of Mexico City by 11 hours and 30 minutes, so a working morning in IST lands the previous evening or night in Mexico City.
