San Jose to IST
San Jose is 12 hours and 30 minutes behind India Standard Time.
Times may vary due to daylight saving time.Quick answer. IST is 13 hours and 30 minutes ahead of San Jose for part of the year and 12 hours and 30 minutes ahead for the rest, because San Jose observes daylight saving time and the other side does not. The gap is 13 hours and 30 minutes during San Jose's standard-time months and 12 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 San Jose 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 San Jose. Columns are hours of the San Jose day.
No standard overlap
A 9–6 day in San Jose 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:
- 5 PM San Jose = 5:30 AM IST — well outside normal hours — 3 hours and 30 minutes beyond
- 4 PM San Jose = 4:30 AM IST — well outside normal hours — 4 hours and 30 minutes beyond
- 9 AM San Jose = 9:30 PM IST — 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 IST build their calendars on different systems, so the days each loses rarely coincide.
Over the next 8 weeks you share 32 working days. 3are lost to a public holiday on one side or the other, leaving 29.
| Date | Who is off | Holiday |
|---|---|---|
| Thursday, October 1, 2026 | India | Gandhi Jayanti |
| Monday, October 12, 2026 | San Jose | Columbus Day |
| Monday, October 19, 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.
Holiday dates for San Jose 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 San Jose and IST?
It depends on the date. IST is 13 hours and 30 minutes ahead of San Jose in January and 12 hours and 30 minutes ahead in July, because San Jose changes clocks for daylight saving time. Use the converter above with the date you actually need.
What time is 9 AM San Jose in IST?
9:00 AM San Jose is 10:30 PM in IST during IST, and 9:30 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 San Jose and IST?
Standard working days do not overlap at all in this pair, so somebody has to stretch. The closest slot is 5 PM San Jose / 5:30 AM IST — 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 San Jose observe daylight saving time?
Yes. San Jose alternates between PST (UTC-8:00) and PDT (UTC-7:00). In 2026, clocks in San Jose 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 San Jose?
In 2026, clocks in San Jose go forward on March 8, 2026 and back on November 1, 2026. Between those dates the gap from India is 12 hours and 30 minutes; outside them it is 13 hours and 30 minutes.
Why does the San Jose–IST difference change during the year?
Because San Jose switches between PST (UTC-8:00) and PDT (UTC-7:00) 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 San Jose and IST actually overlap?
None at standard hours. A 9–6 day in San Jose 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 San Jose and IST line up?
Barely. Over the next eight weeks the two sides share 32 working days, and 3 of those are a public holiday on one side or the other, leaving 29. 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 San Jose ahead of IST?
No, it is the other way around: IST is ahead of San Jose by 12 hours and 30 minutes to 13 hours and 30 minutes.
