PST to IST Conversion Guide

What is PST to IST Conversion?

PST to IST conversion helps you translate time between Pacific Standard Time and India Standard Time zones. PST is UTC-8 and is used during standard time from November to March. IST is always UTC+5:30 and never changes for daylight saving time. The time difference varies between 13.5-14.5 hours depending on whether PST or PDT is observed.

Time Zone Information

Pacific Standard Time (PST): Used on the US West Coast including Los Angeles, San Francisco, Seattle during standard time. Always UTC-8 from first Sunday in November to second Sunday in March.

India Standard Time (IST): Used throughout India including Mumbai, Delhi, Bangalore, Kolkata. Always UTC+5:30 with no daylight saving time adjustments ever implemented.

Time Difference: IST is 13.5 hours ahead of PST, or 12.5 hours ahead of PDT. This creates significant scheduling challenges due to nearly opposite day/night cycles.

Daylight Saving Time Impact

Pacific Time: Switches between PST (UTC-8) in winter and PDT (UTC-7) in summer

India Time: IST never observes daylight saving time and remains UTC+5:30 throughout the year

Variable Difference: The time difference changes from 13.5 hours (PST to IST) to 12.5 hours (PDT to IST) depending on US daylight saving time

Common Conversion Examples

Business Hours (Winter)

PST 8:00 AM → IST 9:30 PM

PST 5:00 PM → IST 6:30 AM (next day)

13.5-hour difference during winter months

Business Hours (Summer)

PDT 8:00 AM → IST 8:30 PM

PDT 5:00 PM → IST 5:30 AM (next day)

12.5-hour difference during summer months

Meeting Planning

Best PST Time: 6:00 AM - 8:00 AM

Converts to IST: 7:30 PM - 9:30 PM

Early morning PST = evening IST

Call Scheduling

PST Evening: 7:00 PM - 11:00 PM

IST Morning: 8:30 AM - 12:30 PM (next day)

PST evening = IST morning (next day)

Conversion Tips & Best Practices

• India uses a single time zone (IST) across the entire country despite its large geographical size

• IST never changes - no daylight saving time adjustments, making it very predictable

• The large time difference means scheduling requires careful consideration of work/sleep hours

• Early morning PST (6-8 AM) aligns well with evening IST (7:30-9:30 PM)

• Late evening PST (9-11 PM) aligns with late morning IST (10:30 AM-12:30 PM next day)

• Remember to account for date changes when converting due to the large time difference

Convert Time Between PST and IST

Trying to match up time zones between the US WEST Coast and India can feel like juggling two clocks that never quite line up. That’s where this PST to IST time conversion tool comes in. Whether you’re scheduling a call with someone in Mumbai from San Francisco or trying to catch a live stream that airs in Delhi, this calculator takes out the mental math and gives you a clear, accurate answer instantly.

What the Time Converter Does and Why It Matters

This tool converts time between Pacific Standard Time (PST) and India Standard Time (IST). You pick a date and time in one timezone, and the tool shows you exactly what that translates to in the other. It also tells you how many hours apart the zones are, shows the UTC offsets, and accounts for daylight saving time automatically if you want it to.

It’s a lifesaver if you work with teams in India from the US, or vice versa. No more second-guessing the difference or missing meetings by half a day.

Step-by-Step: How to Use the Converter

Pick Your Starting Time

Start by selecting a date and time in the input section. You can choose either PST (America/Los_Angeles) or IST (Asia/Kolkata) as your base timezone. Use the dropdown if you want to switch between them.

Adjust Optional Settings

Below the time input, you’ll see options that help tailor the output:

Auto Convert: Automatically updates the result every time you change the input.
Daylight Saving Aware: Adjusts for US daylight saving changes. India doesn’t use DST.
Show UTC Offset: Adds the UTC time difference next to each zone.
Show Seconds: Includes seconds in the display. Handy for precise scheduling.

Convert the Time

Click the “Convert Time” button, and the result appears instantly. You’ll see the converted time, the date it falls on in the new zone, the time difference, and whether daylight saving time is affecting it.

Smart Shortcuts That Save You Clicks

Swap Zones Fast

Use the “Swap” button to reverse the direction of the conversion. If you were converting from PST to IST, this flips it to IST to PST, updating the labels and output accordingly.

Get the Current Time

Click “Now” to load the current time in your selected base timezone. This is great if you’re comparing what time it is right now between locations.

Reset Everything

The “Reset” button clears all your selections and sets the converter back to the current time in PST, ready to start fresh.

Toggle Between 12- and 24-Hour Format

There’s also a “12 Hour / 24 Hour” toggle if you prefer one format over the other. The tool updates all displays on the fly, so you see times the way you’re used to.

What Happens Behind the Scenes

The tool checks if the date you entered falls during US daylight saving time. If it does and DST awareness is enabled, it switches from PST (UTC-8) to PDT (UTC-7). IST never changes, it stays at UTC+5:30 year-round. The tool calculates the UTC time internally and then converts it back out to the other zone, so the results are always aligned no matter what time of year it is.

Common Use: Coordinating Between Bangalore and Seattle

Imagine you’re in Bangalore and you want to schedule a video call with your teammate in Seattle. You’re thinking of 9:00 PM IST, but you’re not sure if that’s too early or too late for them. Pop that into the calculator, and you’ll see it’s 8:30 AM for them during summer, or 7:30 AM in winter. Now you can schedule it without confusion.

A Few Things to Keep in Mind

If you get no result, make sure you’ve picked both a date and a time.
IST never changes for daylight time, but PST does. This means the time difference changes between winter and summer in the US.
There’s a small date shift when you convert between these zones. A call at night in India might actually be on the previous date in the US.
You can use the keyboard: hit Space or Enter to convert, S to swap, N for now, R to reset, and F to switch formats.

Make Time Zones Less of a Puzzle

Working across time zones doesn’t have to be a constant mental calculation. With this converter, you’ll know exactly what time it is in Los Angeles when someone in Delhi schedules a call. Whether it’s for meetings, live broadcasts, or just catching up with friends, this tool helps you stay in sync across continents.
