PST and IST across the year

The difference is not a single number. In July, New Delhi is 12½ hours ahead of Los Angeles; in January it is 13½ hours ahead. That 1 hour swing happens because the two zones do not change their clocks together — and it is why a recurring meeting set once will quietly move for one side after a changeover.

PST: Pacific Time shifts to PDT (UTC−7) during daylight saving and back to PST (UTC−8) in winter. Most people who search for PST mean whatever Pacific Time is right now, which is what this shows.

IST: IST means India Standard Time (UTC+5:30), Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2). This page uses India, which is what the overwhelming majority of searches intend. India does not observe daylight saving, so the offset never changes.

Scheduling between Los Angeles and New Delhi

There is no overlap at all — no hour exists in which both Los Angeles and New Delhi are inside a 9am–6pm day. With 12½ hours between them, that is arithmetic rather than bad luck, and no amount of careful scheduling produces a slot that suits both.

The least-bad compromise is 6:00 pm in Los Angeles, which is 6:30 am in New Delhi. That asks less of Los Angeles than of New Delhi, who would be up before their working day starts. Every alternative is worse for one side than this one is for either.

The better answer, where the work allows it, is to stop meeting synchronously and use the gap deliberately. When Los Angeles finishes at 5:00 pm, it is 5:30 am in New Delhi — the middle of their night, so a handover written at your close waits until their morning — still a full working day of progress, just not an instant one. Going the other way, New Delhi's 5:00 pm is 4:30 am for you.

Used properly that is close to twenty-four hour coverage rather than an obstacle: two working days per calendar day, provided each side ends by writing down where things stand. Reserve live calls for what genuinely needs a conversation, and alternate who takes the 6:00 pm slot when they do.

If you are the one in Los Angeles

New Delhi is ahead of you, which means their day is already ending as yours gets going. By the time you are at your desk at 9:00 am, it is 9:30 pm there — so anything you send in your morning arrives in their evening, after they have stopped. The practical consequence is that your late afternoon is dead time for anything needing a reply from New Delhi: they are asleep, and you will not hear back until your next morning.

So the discipline that pays off is front-loading. Anything New Delhi needs from you should go out early in your day while they are still working; anything you need from them should be asked for before you leave, so it is waiting when you return. Treat their evening as the deadline, not yours.

If this is a recurring meeting, create it with real time zones — a calendar invitation tied to "Los Angeles" rather than to a fixed offset. Both zones' changeovers then take care of themselves. An invitation created as a bare UTC offset will drift by an hour twice a year and nobody will notice until somebody misses a call.

Questions

What time is PST in IST?
IST is 12½ hours ahead of PST in July, and 13½ hours ahead of it in January — the gap changes across the year because at least one of the two observes daylight saving. The converter above uses whichever relationship applies today.
Is the difference between PST and IST the same all year?
No. It is 12½ hours in July and 13½ hours in January. If you are scheduling something recurring — a weekly call, a standing meeting — it will drift by an hour at each daylight-saving changeover unless the invitation was created with real time zones rather than a fixed offset.
What is the best time to schedule a call between Los Angeles and New Delhi?
There is no slot that suits both. The least-bad option is 6:00 pm in Los Angeles, which lands at 6:30 am in New Delhi — New Delhi takes the inconvenience there. Anything closer to the middle of one city's day pushes the other further into the night.
Does IST mean something else?
IST means India Standard Time (UTC+5:30), Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2). This page uses India, which is what the overwhelming majority of searches intend. India does not observe daylight saving, so the offset never changes.
