When it is 09:00 in San Francisco it is 22:30 in New Delhi in January and 21:30 in July. New Delhi is 13 hours 30 minutes ahead San Francisco right now — but it is not constant: the difference is 13 hours 30 minutes ahead in January and 12 hours 30 minutes ahead in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in San Francisco and New Delhi
The two cities side by side. The January column uses the winter offsets (San Francisco UTC−08:00, New Delhi UTC+05:30); the July column uses the summer offsets (San Francisco UTC−07:00, New Delhi UTC+05:30).

The time difference between San Francisco and New Delhi
The difference is not constant. In January New Delhi is 13 hours 30 minutes ahead San Francisco; in July it is 12 hours 30 minutes ahead San Francisco. The difference changes on Sunday, 8 March 2026 (from 13 hours 30 minutes ahead to 12 hours 30 minutes ahead) and Sunday, 1 November 2026 (from 12 hours 30 minutes ahead to 13 hours 30 minutes ahead) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in San Francisco is 22:30 in New Delhi in January and 21:30 in July; 17:00 in San Francisco — the end of the working day — is 06:30 in New Delhi in January and 05:30 in July. To go the other way, subtract it: 09:00 in New Delhi is 19:30 in San Francisco in January. The time difference calculator does the arithmetic for any date, and the UTC to New Delhi page gives the full conversion table for New Delhi.
Meeting overlap between San Francisco and New Delhi
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in San Francisco's working day and shows what time they are in New Delhi.

|---|---|---|
| 09:00 | 21:30 | Yes |
| 10:00 | 22:30 | Yes |

In January the overlap is 2 hours: 15:00, 16:00 San Francisco time. In July it is 2 hours: 09:00, 10:00 San Francisco time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in San Francisco and New Delhi
San Francisco observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−08:00 to UTC−07:00.
New Delhi does not observe daylight saving, so its offset of UTC+05:30 never changes.
The difference changes on Sunday, 8 March 2026 and Sunday, 1 November 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — San Francisco DST 2026 and New Delhi DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 15:00–17:00 in San Francisco (04:30–06:30 in New Delhi). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
In July the best windows are 09:00–11:00 in San Francisco (21:30–23:30 in New Delhi) — the same logic, with the July offsets.
Calling and travel notes
When it is 09:00 in San Francisco it is 22:30 in New Delhi in January; when it is 12:00 in San Francisco it is 01:30 in New Delhi; when it is 17:00 in San Francisco it is 06:30 in New Delhi. The difference is 12 hours or more, so the two cities are on different dates for part of the day: when it is Monday morning in San Francisco, it is still Sunday in New Delhi if New Delhi is behind, or already Monday evening if it is ahead. Always state the date as well as the time when you schedule across this pair. Scheduling between the Americas and Asia is the hardest case in time-zone work: the difference is 12 hours or more, so one side's working day is the other's night. The only workable approach is to meet at the edge of the day — early morning in San Francisco and evening in New Delhi, or the reverse — and to keep the meeting short. Rotate the awkward hour week by week, or the same side will always be the one giving up its evening. Record the meeting and share notes, so the side that could not attend can still follow the decision.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in San Francisco and time in New Delhi — explain each city's time zone, and the DST pages — San Francisco DST 2026 and New Delhi DST 2026 — give the exact change dates.
