What is the time difference between PST and IST?
IST is 9 hours ahead of PST. In everyday terms, once you know the time on one side you just add 9 hours to get the other — so a call between Los Angeles and Dublin is always 9 hours apart.
What's the current time in IST?
Right now the time in Irish Standard Time (IST) is Monday, June 29, 2026 · 6:53:56 PM. It ticks every second, so you’re always looking at the live IST clock.
And what time is it in PST?
And in Pacific Standard Time (PST), it’s currently Monday, June 29, 2026 · 9:53:56 AM. Compare the two and the 9 hours gap is easy to see.
Planning a meeting across PST and IST?
For example, a 9:00 AM PST meeting takes place at 6:00 PM IST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the PST–IST difference?
The labels PST and IST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 9 hours gap usually holds steady right through the year.
How accurate is this PST to IST conversion?
We don’t guess. PST and IST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Do PST or IST use daylight saving time?

Why might the real-world PST–IST difference change during the year?
The labels PST and IST are fixed offsets, so this converter is always exact. But Pacific Standard Time's region switches between standard and summer time, so for part of the year you may actually want PDT to IST. Always check which label a region is currently using before you schedule.
