US-Australia Time Difference After Nov. 1, 2026: Sydney Is 16 Hours Ahead of New York

Sydney is 16 hours ahead of New York from Sunday, Nov. 1, 2026, when US clocks go back at 2 a.m. local time, according to the National Institute of Standards and Technology (NIST). The gap was 15 hours from Oct. 4, when New South Wales (NSW) started daylight saving, and it moves again on March 14 and April 4, 2027. The hour differences in this story are our calculation from the Internet Assigned Numbers Authority (IANA) Time Zone Database, the data that browsers and phones use.

Because the two hemispheres change clocks on different dates, the gap shifts three times between Nov. 1, 2026 and April 2027. A one-page printable of the change dates is on this page.

When do the clocks change in the US, Australia and New Zealand?

NIST says that “during 2026, daylight saving time is in effect from March 8 at 2 a.m. (local time) to November 1 at 2 a.m. (local time).” Its rule is that daylight saving time begins at 2 a.m. on the second Sunday of March, which makes the next start Sunday, March 14, 2027 (our calculation from that rule).

The NSW Government says daylight saving in New South Wales started on Sunday, 4 October 2026 at 2 a.m. Australian Eastern Standard Time (AEST) and ends on Sunday, 4 April 2027 at 3 a.m. Australian Eastern Daylight Time (AEDT). The New Zealand Government says daylight saving there “starts each year at 2am on the last Sunday in September, and ends at 3am on the first Sunday in April.” That gives Sunday, Sept. 27, 2026 and Sunday, April 4, 2027.

What is the time difference between Sydney and New York after Nov. 1?

Sydney is 16 hours ahead of New York from Nov. 1, 2026 until March 13, 2027. In the tz database, Sydney is on UTC+11 in that period, where UTC is Coordinated Universal Time, and New York is on Eastern Standard Time (EST), UTC-5. Eastern Daylight Time (EDT) is UTC-4. Melbourne, Canberra and Hobart share Sydney’s offsets in the database.

The table shows how many hours each place is ahead of each US city from Nov. 1, 2026 to March 13, 2027. A value of 15.5 means 15 hours 30 minutes. Phoenix and Honolulu figures also come from the tz database.

Place (UTC offset)	New York	Chicago	Denver	Phoenix	Los Angeles	Anchorage	Honolulu
Sydney, Melbourne, Canberra, Hobart (UTC+11)	16	17	18	18	19	20	21
Adelaide (UTC+10:30)	15.5	16.5	17.5	17.5	18.5	19.5	20.5
Brisbane (UTC+10)	15	16	17	17	18	19	20
Darwin (UTC+9:30)	14.5	15.5	16.5	16.5	17.5	18.5	19.5
Perth (UTC+8)	13	14	15	15	16	17	18
Auckland (UTC+13)	18	19	20	20	21	22	23

The NSW Government says that “New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory observe daylight saving.” Queensland, Western Australia and the Northern Territory are not on that list, so Brisbane, Perth and Darwin keep one offset in our table.

How does the gap change from October 2026 to April 2027?

The gap changes on four dates. Before Oct. 4, Sydney was 14 hours ahead of New York (our calculation). The next table compares New York and Los Angeles with Sydney and Auckland in each period.

Period	Sydney vs New York	Sydney vs Los Angeles	Auckland vs New York	Auckland vs Los Angeles
Oct. 4 to Oct. 31, 2026	15	18	17	20
Nov. 1, 2026 to March 13, 2027	16	19	18	21
March 14 to April 3, 2027	15	18	17	20
From April 4, 2027	14	17	16	19

Auckland’s 17-hour gap with New York began on Sept. 27, a week before Sydney’s change, because New Zealand started daylight saving first. After April 4, 2027, Brisbane stays 14 hours ahead of New York, while Sydney falls back to the same gap.

What does the gap mean for a call or a flight?

Sydney is on the next calendar day for much of the US day. From Nov. 1, 2026, any time from 8 a.m. Eastern Time (ET) to midnight ET is already the following date in Sydney (our calculation). Check the date as well as the hour before you set a meeting.

If it is this in Sydney	New York (ET)	Los Angeles (Pacific Time, PT)
9 a.m. Monday, Nov. 1, 2026 to March 13, 2027	5 p.m. Sunday	2 p.m. Sunday
9 a.m. Monday, Oct. 4 to Oct. 31, 2026	6 p.m. Sunday	3 p.m. Sunday

If it is this in New York	Sydney	Auckland
9 a.m. Monday, from Nov. 1, 2026 to March 13, 2027	1 a.m. Tuesday	3 a.m. Tuesday
9 a.m. Monday, Oct. 4 to Oct. 31, 2026	12 a.m. Tuesday	2 a.m. Tuesday

Which stories cover other places that change clocks?

The same Nov. 1 change shifts the gap with Mexico, whose time zones mostly stay put; see our Mexico time difference story. For the US change itself, read when daylight saving time ends on Nov. 1, 2026 and the daylight saving time guide. For the UK and Europe, the time difference story covers that gap.

Quick checklist for Nov. 1

• Find your US city in the main table and read the hours ahead for the Australian or New Zealand city.
• Recheck any recurring call with Sydney: the gap grows by one hour on Nov. 1.
• Note March 14, 2027 and April 4, 2027, the next two dates when the gap changes.
• Mark Nov. 1 on a November 2026 printable calendar or a printable weekly calendar.
