Convert PST to IST
See the current PST to IST time difference, compare hours side by side, and plan meetings across Pacific and India time.
How PST to IST Works
PST is UTC-8 and IST is UTC+5:30, so IST is 13 hours 30 minutes ahead of Pacific Standard Time. This converter applies the correct offset automatically and reflects DST changes when Pacific Time switches seasonally.

How to Convert PST to IST
Open the PST to IST page: Visit https://www.xconvert.com/time-converter/pst-to-ist-converter to load a comparison grid with PST and IST already in view. This is useful when you are planning a call between a West Coast team in the United States or Canada and colleagues in India, Ireland, or Israel who follow IST, especially for software delivery, customer support coverage, or vendor coordination.
Add comparison cities: Click + Add City and search for cities that matter to your workflow, such as Los Angeles for Pacific business hours, Mumbai for India-based operations, or Tel Aviv for teams working on Israel schedules. This helps if you manage cross-border work in technology, outsourcing, logistics, or consulting and need to see how PST lines up against multiple IST locations on one screen.
Select a time range on the grid: Click Select, then drag across the colored timeline on the PST row to highlight a meeting window in purple; you can resize it with the left and right handles or move the whole block by dragging the center. For example, dragging from 9:00 PST to 12:00 PST shows 22:00 IST to 1:00 IST the next day, which makes it clear that a late-morning Pacific meeting lands late at night for India-based participants.
Export and share the result: Once a time range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is practical when a distributed team needs a confirmed handoff slot, such as sending an ICS file to engineering and support teams so everyone sees the meeting in their own local calendar without manually converting PST to IST.
Understanding the PST to IST Time Difference
PST is Pacific Standard Time, UTC-8, and IST is India Standard Time, UTC+5. IST is 13 hours ahead of PST, so the conversion moves significantly forward, and afternoon PST times often become the next calendar day in IST.
The most useful reference points are straightforward: 9:00 PST = 22:00 IST, 12:00 PST = 1:00 IST (next day), 15:00 PST = 4:00 IST (next day), and 18:00 PST = 7:00 IST (next day). These examples show why PST-to-IST scheduling often crosses midnight and why teams need to confirm not just the hour but also the date.
DST matters because PST is a standard-time abbreviation and its DST counterpart is PDT, while IST is a standard-time abbreviation and its DST counterpart is IDT. That means the difference can change during the parts of the year when Pacific locations switch away from PST to PDT, so anyone scheduling recurring meetings across spring and summer months should verify whether the meeting is still being set in PST or has shifted to the daylight counterpart.
PST is used in parts of Canada, Mexico, the Philippines, and the United States, while IST is used in India, Ireland, and Israel. In practical terms, this conversion is common for offshore development, customer service escalation, cloud operations, and procurement work where North American teams start the day as South Asian teams are already late into the evening.
Best Times for Calls and Meetings Between PST and IST
Because IST is 13 hours ahead of PST, the most workable meeting windows are usually found by using the earlier part of the PST day before IST moves too deep into the night. A 9:00 PST meeting becomes 22:00 IST, which is late but still possible for urgent project reviews, production incident calls, or end-of-day status updates.
A 12:00 PST meeting becomes 1:00 IST the next day, which is usually too late for routine business meetings unless the conversation is time-sensitive, such as a release freeze, infrastructure incident, or financial close task. The same pattern becomes even harder later in the Pacific day: 15:00 PST = 4:00 IST (next day) and 18:00 PST = 7:00 IST (next day), both of which fall outside normal work hours for most office teams.
For recurring collaboration, the most realistic overlap usually comes from keeping Pacific meetings as early as possible and using the grid to compare the green work-hour blocks against the yellow evening blocks in IST. That visual comparison is especially useful for remote engineering teams, BPO operations, and account managers who need a narrow handoff window without pushing India-based staff into overnight schedules.
If you are coordinating between a California product team and an India engineering team, the examples above show that even a standard Pacific morning can already be late evening in IST. That makes PST mornings better for one-off reviews and escalations, while asynchronous updates, shared documents, and recorded walkthroughs are often better for anything that would otherwise land after 22:00 IST.
Frequently Asked Questions
What is the time difference between PST and IST?
IST is 13 hours ahead of PST. That means when the workday begins in Pacific Standard Time, teams on IST are already much later in their day, and midday Pacific time often pushes into the next calendar day on the IST side.
When is 9 AM PST in IST?
9:00 PST = 22:00 IST. This is a useful benchmark for scheduling because it shows that a standard morning meeting on the Pacific side becomes a late-evening meeting for teams working on IST.
When is 12 PM PST in IST?
12:00 PST = 1:00 IST the next day. This next-day shift is important for calendar invites, project deadlines, and support coverage because the meeting is no longer on the same date for IST participants.
Does the difference between PST and IST change during DST?
Yes, it can change because PST is a standard-time abbreviation and its DST counterpart is PDT, while IST is a standard-time abbreviation and its DST counterpart is IDT. In the months when Pacific locations move from PST to PDT, recurring meetings should be reviewed carefully so teams do not assume the same PST-to-IST gap still applies.
What is the best meeting time between PST and IST?
Using the examples here, 9:00 PST = 22:00 IST is one of the more practical options because it is late evening rather than deep overnight. By contrast, 12:00 PST = 1:00 IST, 15:00 PST = 4:00 IST, and 18:00 PST = 7:00 IST all fall into the next day and are much harder for normal business meetings.
Why does PST to IST often move to the next day?
The reason is the large 13-hour lead that IST has over PST. Once you move beyond the early Pacific morning, the converted IST time quickly passes midnight, which is why 12:00 PST, 15:00 PST, and 18:00 PST all become next-day times in IST.
Is PST the same as PDT when converting to IST?
No. PST is the standard-time abbreviation, while PDT is its daylight counterpart. If a meeting invite says PST specifically, use the PST-to-IST relationship shown here; if it says PDT instead, the meeting should be reviewed separately before confirming the time with participants.
