PST to IST Converter

Use this PST to IST Converter to convert Pacific Time to India Standard Time for meetings, remote work, webinars, interviews, and international calls.

Quick Answer: Pacific Standard Time (PST) is UTC−8. Indian Standard Time (IST) is UTC+5:30. IST is 13 hours and 30 minutes ahead of PST. During US Daylight Saving Time — when Pacific time becomes PDT (UTC−7) — the difference narrows to 12 hours and 30 minutes. India does not observe Daylight Saving Time, so IST is fixed year-round.

Current Time Difference Between PST and IST Right Now

The live converter above shows the exact current time in both Pacific Time and India right now, calculated automatically from your device’s clock. At any given moment, India is either 12 hours 30 minutes or 13 hours 30 minutes ahead of the US West Coast — never anything in between, and never in the opposite direction. If you are checking “what time is it in India compared to California right now,” the answer is always one of these two values depending on whether the US West Coast is currently observing PST or PDT. The section below explains exactly which one applies and when it changes.

Why PST to IST Is Either 12:30 or 13:30 Hours

This is the most common confusion with this conversion — and the reason most converters give you the wrong answer half the year.

PST (Pacific Standard Time) is UTC−8:00. The US West Coast observes PST during winter — from the first Sunday in November through the second Sunday in March.

PDT (Pacific Daylight Time) is UTC−7:00. From the second Sunday in March through the first Sunday in November, the US West Coast moves to PDT. Most people still call it “PST” when they mean Pacific time — but the actual offset has changed.

IST (Indian Standard Time) is UTC+5:30, fixed year-round. India has never observed Daylight Saving Time.

This creates two different answers depending on the time of year:

The converter above automatically detects which offset applies based on the date you select — so your result is always correct.

What Is PST (Pacific Standard Time)?

Pacific Standard Time (PST) is UTC−8, used across the western United States and Canada during winter. Major cities on Pacific time include Los Angeles, San Francisco, San Diego, San Jose, Seattle, Portland, Las Vegas, and Vancouver.

From mid-March through early November, these cities switch to Pacific Daylight Time (PDT, UTC−7). When people search “PST to IST,” they usually mean whichever Pacific offset is currently active in their city — which is why this converter defaults to real-world Pacific time, auto-detecting PST or PDT based on the date.

States fully or primarily on Pacific Time: California, Washington, Oregon, and Nevada. Parts of Idaho also observe Pacific time.

What Is IST (Indian Standard Time)?

Indian Standard Time (IST) is UTC+5:30 — exactly 5 hours and 30 minutes ahead of Coordinated Universal Time. It is the single time zone used across all of India.

India adopted a unified national time zone in 1905, aligned to the 82.5° East meridian passing through Allahabad, Uttar Pradesh. This produces the unusual 30-minute offset rather than a whole-hour increment. India has never observed Daylight Saving Time — IST stays at UTC+5:30 every day of the year.

Key cities on IST: Mumbai, New Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad.

Best Times to Schedule Meetings Between PST and IST

The PST–IST gap is large (12.5 to 13.5 hours), making real-time overlap during standard business hours nearly impossible. Two practical options exist.

Option A — Early Pacific morning:

Option B — Late Pacific night (US team stays late):

Recommended window: 6:00 AM – 7:30 AM Pacific Time. This equals 6:30 PM – 8:30 PM IST — both sides in reasonable hours. This is the most widely used solution for US West Coast–India remote teams, since it asks the Pacific side for an early start rather than a very late night.

How the Converter Calculates PST to IST

The converter follows this logic for every time you enter:

1. Take the Pacific date and time you input
2. Check whether that date falls inside US Daylight Saving Time (second Sunday in March through first Sunday in November)
3. Apply the correct Pacific offset — UTC−8 for PST, UTC−7 for PDT
4. Convert to UTC
5. Add 5 hours and 30 minutes (UTC+5:30) to get IST

This is more accurate than adding a fixed offset to every date. Simple converters that always add 13.5 hours give you the wrong answer for roughly 8 months of the year.

The formulas:

• Fixed PST → IST: add 13 hours 30 minutes
• PDT → IST: add 12 hours 30 minutes

FAQS

What is the time difference between PST and IST?

The time difference between Pacific Standard Time (PST) and Indian Standard Time (IST) is 13 hours and 30 minutes — IST is ahead. During US Daylight Saving Time (PDT, second Sunday in March through first Sunday in November), the difference narrows to 12 hours and 30 minutes because the US West Coast shifts to UTC−7 while India stays at UTC+5:30 year-round.

What is 9 AM PST in IST?

9:00 AM fixed PST equals 10:30 PM IST. During Pacific Daylight Time (PDT), 9:00 AM Pacific time equals 9:30 PM IST. The correct answer depends on the date — use the converter above for date-accurate results.

What is 10 AM PST in IST?

10:00 AM fixed PST equals 11:30 PM IST. During PDT, 10:00 AM Pacific time equals 10:30 PM IST.

What is 8 AM PST in IST?

8:00 AM fixed PST equals 9:30 PM IST. During PDT, 8:00 AM Pacific time equals 8:30 PM IST.

What is 11 AM PST in IST?

11:00 AM fixed PST equals 12:30 AM IST on the following day. During PDT, 11:00 AM Pacific time equals 11:30 PM IST on the same day.

What is 12 PM (noon) PST in IST?

12:00 PM fixed PST equals 1:30 AM IST on the following day. During PDT, noon Pacific time equals 12:30 AM IST on the following day.

What is 6 AM PST in IST?

6:00 AM fixed PST equals 7:30 PM IST. During PDT, 6:00 AM Pacific time equals 6:30 PM IST. This is often the most practical Pacific-morning slot for reaching India in the evening.

Why does PST to IST sometimes show 12 hours 30 minutes instead of 13 hours 30 minutes?

This happens when the US West Coast is on PDT (Pacific Daylight Time, UTC−7) rather than fixed PST (UTC−8). The US observes PDT from the second Sunday in March through the first Sunday in November. India does not change its clocks, so IST stays at UTC+5:30 year-round — meaning the gap shrinks during US summer.

Why is there a 30-minute increment in the PST to IST difference?

India’s UTC+5:30 offset includes a 30-minute increment because IST was established to align with the 82.5° East meridian passing through Allahabad. India chose a single national time zone rather than splitting the country, and the geographic midpoint of the country falls at a longitude that corresponds to a half-hour offset. Fixed PST is UTC−8:00, so the total gap is 13 hours 30 minutes (or 12 hours 30 minutes during PDT).

Does India observe Daylight Saving Time?

No. Indian Standard Time (IST) is UTC+5:30 year-round. India has never observed Daylight Saving Time and has no seasonal clock changes. This is why the PST–IST difference changes seasonally — the change is entirely on the US side, not the Indian side.

What cities use Pacific Standard Time?

Major cities on Pacific time include Los Angeles, San Francisco, San Diego, San Jose, Seattle, Portland, Las Vegas, and Sacramento. In Canada, Vancouver and Victoria observe Pacific time. During winter (November through mid-March) these cities observe PST (UTC−8). During summer (mid-March through November) they observe PDT (UTC−7).

Is “Pacific Time” the same as PST?

Not exactly. “Pacific Time” (PT) is the general label for the US West Coast time zone. In winter, Pacific Time is PST (UTC−8). In summer, it becomes PDT (UTC−7). When people say “PST to IST” they usually mean whichever Pacific offset their city is currently on — which is why this converter defaults to real-world Pacific time rather than fixed UTC−8.

What is 5 PM PST in IST?

5:00 PM fixed PST equals 6:30 AM IST on the following day. During PDT, 5:00 PM Pacific time equals 5:30 AM IST the next day.

What is 6 PM PST in IST?

6:00 PM fixed PST equals 7:30 AM IST on the following day. During PDT, 6:00 PM Pacific time equals 6:30 AM IST the next day.

What is 7 PM PST in IST?

7:00 PM fixed PST equals 8:30 AM IST on the following day. During PDT, 7:00 PM Pacific time equals 7:30 AM IST the next day.

Is San Francisco 13 hours ahead of India?

No, it is the opposite. India (IST) is ahead of San Francisco (Pacific Time), not the other way around. San Francisco is 13 hours and 30 minutes behind India during US winter (PST), or 12 hours and 30 minutes behind during US summer (PDT).

What time is it in India right now compared to San Francisco?

India is always either 12 hours 30 minutes or 13 hours 30 minutes ahead of San Francisco, depending on whether San Francisco is currently on Pacific Standard Time (PST, UTC−8, used November through mid-March) or Pacific Daylight Time (PDT, UTC−7, used mid-March through November). India does not observe Daylight Saving Time, so its UTC+5:30 offset never changes — only the US side shifts. Use the live converter above for the exact current time in both locations.

Does the PST to IST time difference change during the year?

Yes, but only because of the US side. The PST to IST difference is 13 hours 30 minutes during US winter (when Pacific Time is PST, UTC−8) and 12 hours 30 minutes during US summer (when Pacific Time is PDT, UTC−7). India’s offset stays at UTC+5:30 every day of the year. The transition dates are the second Sunday in March (gap narrows to 12:30) and the first Sunday in November (gap widens back to 13:30).

About PST and IST

Pacific Time is used across the western United States, western Canada, and parts of Mexico’s Baja California. It alternates between Pacific Standard Time (UTC−8:00) from November through mid-March and Pacific Daylight Time (UTC−7:00) from mid-March through November, following the US Daylight Saving Time schedule under the Energy Policy Act of 2005. Common alternative names include PT, West Coast Time, and California Time.

Indian Standard Time (IST) is UTC+5:30 — a half-hour offset that places India 5 hours and 30 minutes ahead of Coordinated Universal Time. India uses a single time zone across its entire territory and has done so since 1905. According to the IANA Time Zone Database — the official global standard used by all major operating systems and browsers — India Standard Time is identified by the timezone identifier Asia/Kolkata, while Pacific time is identified as America/Los_Angeles.

The U.S. Federal Aviation Administration’s official time zone table confirms Pacific Standard Time as UTC−8 and Pacific Daylight Time as UTC−7.
