About Aliso Viejo Time Zone
Aliso Viejo uses the America/Los_Angeles IANA time zone, the standard database name for Pacific Time in much of California and the US West Coast. The city is in Orange County, California, so it follows the same clock rules as Los Angeles, San Diego, Irvine, and other Southern California business centers.
During standard time, Aliso Viejo operates on UTC-8, known as Pacific Standard Time (PST). During daylight saving time, it changes to UTC-7, known as Pacific Daylight Time (PDT). In the United States, daylight saving time typically begins on the second Sunday in March and ends on the first Sunday in November; for example, clocks move forward on March 9, 2025 and move back on November 2, 2025.
Aliso Viejo is 1 hour behind Denver, 2 hours behind Chicago, and 3 hours behind New York when US daylight rules are aligned. It is in the westernmost major continental US time zone used by large population centers, which makes it important for companies coordinating with East Coast headquarters, Asia-Pacific suppliers, and European customers from California offices.

Time Differences from Aliso Viejo
Aliso Viejo’s time difference depends on whether Pacific Time is on standard time or daylight saving time, and some international cities change clocks on different dates. For practical scheduling, it is best to compare by date, especially in March and October when US and European DST transitions do not happen on the same weekend.
New York: Aliso Viejo is usually 3 hours behind New York. When it is 9:00 AM in Aliso Viejo, it is typically 12:00 PM in New York, which makes late-morning California calls suitable for same-day East Coast business meetings.
London: Aliso Viejo is usually 8 hours behind London when both regions are on standard time, and often 7 hours behind when both are on daylight time. When it is 9:00 AM in Aliso Viejo, it is usually 5:00 PM in London in winter or 4:00 PM in London in summer, which creates a narrow but usable overlap for legal, finance, and agency calls.
Tokyo: Aliso Viejo is generally 17 hours behind Tokyo during PST and 16 hours behind during PDT because Japan does not observe daylight saving time. When it is 9:00 AM in Aliso Viejo, it is usually 2:00 AM the next day in Tokyo during standard time, so most live meetings require California evening or Japan morning scheduling.
Sydney: Aliso Viejo is commonly 19 hours behind Sydney or 17 hours behind depending on each region’s seasonal clock setting, because Australia’s DST calendar differs from the US. When it is 9:00 AM in Aliso Viejo, it can be 4:00 AM the next day in Sydney or 2:00 AM the next day in other parts of the year, so teams often choose late afternoon California time for Australia coordination.
Dubai: Aliso Viejo is typically 12 hours behind Dubai during PST and 11 hours behind during PDT, since the UAE does not use daylight saving time. When it is 9:00 AM in Aliso Viejo, it is usually 9:00 PM in Dubai during standard time or 8:00 PM in Dubai during daylight time, making California mornings one of the few realistic windows for Gulf-region business calls.
Frequently Asked Questions
What time zone is Aliso Viejo in?
Aliso Viejo is in the America/Los_Angeles time zone, which is the IANA time zone identifier for Pacific Time in California. In everyday use, this means the city follows Pacific Standard Time (PST, UTC-8) in winter and Pacific Daylight Time (PDT, UTC-7) in the daylight saving period.
Does Aliso Viejo observe daylight saving time?
Yes, Aliso Viejo observes daylight saving time because it follows California and broader US Pacific Time rules. Clocks move forward on the second Sunday in March and move back on the first Sunday in November, so the local UTC offset changes from UTC-8 to UTC-7 for part of the year.
What is the time difference between Aliso Viejo and New York?
Aliso Viejo is generally 3 hours behind New York because New York follows Eastern Time while Aliso Viejo follows Pacific Time. For example, when it is 8:00 AM in Aliso Viejo, it is usually 11:00 AM in New York, which is why California teams often schedule cross-country meetings in their late morning to catch New York before the end of the business day.
What is the best time to call Aliso Viejo from another US city or from the UK?
From most US cities, the best time to call Aliso Viejo is usually between 9:00 AM and 3:00 PM Pacific Time, which translates to 12:00 PM to 6:00 PM in New York and 10:00 AM to 4:00 PM in Denver. From the UK, a practical window is often 4:00 PM to 6:00 PM London time for reaching Aliso Viejo in the morning, especially for sales, legal, or operations calls that need same-day responses.
What is the UTC offset for Aliso Viejo?
Aliso Viejo uses UTC-8 during standard time and UTC-7 during daylight saving time. If you are scheduling software deployments, international flights, or calendar invites, this seasonal offset matters because a fixed UTC meeting can appear one hour earlier or later locally after the DST transition.
What currency does Aliso Viejo use?
Aliso Viejo uses the US Dollar (USD) because it is located in the United States. This is relevant for travelers booking hotels in Orange County, businesses issuing invoices to California clients, and international shoppers comparing prices or exchange rates.
Is Aliso Viejo the same time as Los Angeles?
Yes, Aliso Viejo and Los Angeles use the same time zone: America/Los_Angeles. Both cities follow Pacific Time and switch between PST and PDT on the same dates, so there is no time difference between them for commuting, business calls, or event planning.
Why does the time difference between Aliso Viejo and London sometimes change?
The difference changes because the United States and the United Kingdom start and end daylight saving time on different dates. In the weeks around March and late October, the gap may temporarily shift by one hour, which can affect meeting times for California-UK teams if calendars are not updated carefully.
