What this tool actually does

This calculator converts any chosen time and date between Pacific Time and AEST. You can input your time in either zone, and the tool will automatically display the equivalent in the other. It knows when daylight saving time is in effect for Pacific Time and adjusts accordingly. AEST stays fixed all year, so there’s no need to worry about seasonal changes on the Australian side.

Who this is built for

If you’re part of a global team spread between California and Sydney or hosting events across these regions, this tool helps you stay coordinated. From software sprints and video calls to publishing deadlines or online classes, you'll always know the right hour to show up, without confusion over calendar math.

Here’s how you use it

Choose your starting time

Use the calendar and clock to set your base time. You can pick Pacific Time or AEST as your input zone. Select it from the dropdown, and the calculator will do the rest.

Want updates as you type?

Leave the “Auto Convert” box checked. As you change the date or time, the conversion updates right away. Prefer a manual approach? Uncheck the box and click “Convert Time” only when you're ready.

Switch directions in one click

The “Swap” button flips the input and output zones without clearing your time entry. Handy if you’re double-checking both ends of a meeting invite.

Get the current time fast

Need to know what time it is right now in either location? Click “Now” and the tool grabs the current time for the selected input zone. Quick and accurate.

Display time how you like it

Prefer a 24-hour clock? Tap the “Time Format” button to toggle between 12 and 24-hour formats. Everything updates across the board.

What’s happening behind the scenes

Daylight saving time for Pacific Time

PST (UTC-8) becomes PDT (UTC-7) from the second Sunday in March until the first Sunday in November. The converter tracks these changes and adjusts the output based on your selected date.

AEST is steady all year

Australian Eastern Standard Time (UTC+10) doesn’t observe daylight saving in this tool. That means the time difference between zones is always either 18 or 17 hours, depending on the Pacific season.

See exact UTC offsets

If you check the “Show UTC Offset” box, you’ll see offsets like -07:00 or +10:00 listed in the results. This is useful when sending invites that include global time information.

Make sure you don’t get caught out

Daylight saving time changes based on region. Pacific Time shifts, AEST stays the same.
The time gap is big—17 to 18 hours. This often means you're scheduling into the next day.
Morning in California often lines up with late night in Australia. Know your overlap windows.
To avoid AM/PM mix-ups, switch to 24-hour format during scheduling.
Always double-check the date. A Monday evening PST may already be Tuesday morning AEST.

Here’s where this really helps

If you’re organizing a product launch with developers in San Francisco and partners in Sydney, this tool makes sure your launch meeting is actually on the same day for everyone. Say you plan it for 4:00 PM PDT on July 12. Plug that in, and you’ll see it’s 9:00 AM AEST on July 13, perfect for the start of the workday in Australia. You can set, confirm, and send invites in minutes, with full confidence that everyone’s in sync.

Keep your timing aligned across continents

The PST to AEST converter takes care of the messy timezone logic, so you don’t have to. Whether you’re working across offices, launching events, or simply planning a call, it gives you a clear, accurate way to align your calendar. You pick the time, and the tool keeps it all straight. Simple, reliable, and built for everyday use.
