How to Convert PST to AEST
Open the PST to AEST page: Go to https://www.xconvert.com/time-converter/pst-to-aest-converter. The page is set up for Pacific Standard Time and Australian Eastern Standard Time, which is useful when you are planning a call between the U.S. or Canada West Coast and eastern Australia for client support, software releases, or cross-border operations.
Add comparison cities: Click + Add City and add cities that commonly work with PST and AEST schedules, such as Los Angeles, Sydney, and Brisbane. This helps if you are coordinating media, SaaS, logistics, or customer service teams that need to compare Pacific business hours with Australia’s east coast working day.
Select a working time range on the grid: Click Select, then drag across the colored timeline to highlight a PST time block in purple. For example, drag from 9:00 PST to 12:00 PST to see that this maps to 3:00 AEST to 6:00 AEST the next day, which quickly shows whether a California morning meeting lands in an early Australian business window.
Export and share the result: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful when sending a confirmed meeting slot to a distributed team, because everyone can receive the same time block and place it into their own workflow without rechecking the conversion manually.
Understanding the PST to AEST Time Difference
PST is UTC-8 and AEST is UTC+10, so AEST is 18 hours ahead of PST. In practical terms, that means a workday in Pacific Standard Time often appears on the next calendar day in Australian Eastern Standard Time, which is why cross-Pacific scheduling needs careful date awareness as well as hour conversion.
The most useful reference points are straightforward: 9:00 PST = 3:00 AEST (next day), 12:00 PST = 6:00 AEST (next day), 15:00 PST = 9:00 AEST (next day), and 18:00 PST = 12:00 AEST (next day). These examples show the pattern clearly: late morning and afternoon in PST shift into the following morning in eastern Australia, which is often the most practical handoff window for product, support, and operations teams.
Both abbreviations are standard-time labels, not year-round clocks. PST is the standard-time abbreviation, and its daylight counterpart is PDT; AEST is the standard-time abbreviation, and its daylight counterpart is AEDT. During months when North America and parts of Australia move onto daylight saving time, the difference can change, so the PST-to-AEST relationship applies specifically when both sides are on these standard-time offsets rather than their daylight variants.
PST is used in parts of the United States, Canada, Mexico, and the Philippines, while AEST is used in Australia. For businesses working across these regions, the 18-hour gap is large enough that many meetings are not true same-day meetings; they are typically evening-to-next-morning or afternoon-to-next-day-midday conversions.
Best Times for Calls and Meetings Between PST and AEST
Because AEST is 18 hours ahead of PST, the most workable meeting windows usually come from afternoon or early evening in PST, which becomes morning or midday the next day in AEST. This is especially relevant for teams handling software deployments, agency reviews, finance approvals, and customer support escalations between North America and Australia.
A very practical example is 15:00 PST = 9:00 AEST (next day). That pairing creates a clean transition from a mid-afternoon Pacific meeting into a standard morning start in eastern Australia, making it one of the most realistic options for recurring business calls.
Another strong option is 18:00 PST = 12:00 AEST (next day). This works well when a Pacific team can meet near the end of its day and the Australian side can join around midday, which is often easier than asking either side to join before dawn or late at night.
Earlier PST times are usually less convenient for normal office schedules in Australia. For instance, 9:00 PST = 3:00 AEST (next day) and 12:00 PST = 6:00 AEST (next day), which place the Australian side in very early morning hours before a typical business day begins. Those slots can still be useful for urgent production incidents, overnight trading coordination, or travel-related operations, but they are less suitable for routine weekly meetings.
If you need a repeatable cross-border schedule, the safest pattern is to test a purple selection block across late PST hours on the grid and compare it against the AEST row visually. That makes it easy to spot whether your proposed slot lands in green working-hour blocks for both sides before you export it to calendar tools.
Frequently Asked Questions
What is the time difference between PST and AEST?
AEST is 18 hours ahead of PST. That means when a team in Pacific Standard Time is still on the current day, a team in Australian Eastern Standard Time is often already operating on the next calendar day, which is critical when booking meetings, deadlines, and handoffs.
When is 9 AM PST in AEST?
9:00 PST = 3:00 AEST (next day). This conversion is useful for understanding why a standard Pacific morning meeting does not usually align with normal office hours in eastern Australia, since it lands very early the following morning there.
When is 12 PM PST in AEST?
12:00 PST = 6:00 AEST (next day). For remote teams, this means a Pacific lunchtime discussion becomes an early-start Australian meeting on the next day, which may work for urgent coordination but is usually early for routine business calls.
When is 3 PM PST in AEST?
15:00 PST = 9:00 AEST (next day). This is one of the most practical conversions for recurring meetings because it places the Australian side at the start of a normal workday while keeping the Pacific side within regular afternoon office hours.
When is 6 PM PST in AEST?
18:00 PST = 12:00 AEST (next day). This slot is often useful for end-of-day handoffs from Pacific teams to Australia-based colleagues, especially in support, operations, and project delivery environments where work passes between regions.
Does the difference between PST and AEST change during DST?
Yes, it can change during daylight saving periods because PST and AEST are both standard-time abbreviations, while their daylight counterparts are PDT and AEDT. The 18-hour difference applies specifically to PST and AEST; during months when one or both regions are observing daylight saving time, you need to use the appropriate daylight abbreviation instead of assuming the same gap.
What is the best meeting time between PST and AEST?
The best options usually come from later PST hours, because they become morning or midday the next day in AEST. Based on the examples, 15:00 PST = 9:00 AEST (next day) and 18:00 PST = 12:00 AEST (next day) are the strongest choices for normal business meetings, while 9:00 PST = 3:00 AEST (next day) and 12:00 PST = 6:00 AEST (next day) are generally better reserved for urgent or exceptional coordination.
Which countries use PST and AEST?
PST is used in Canada, Mexico, the Philippines, and the United States, while AEST is used in Australia. This matters for international scheduling because a Pacific-facing business may be dealing with multiple countries under the PST label, while AEST is specifically tied to Australian operations on the east coast standard-time offset.
