Sydney is 14 to 16 hours ahead of Toronto, depending on the time of year. If you are both awake 7 am to 11 pm, a January weekday gives you 8 hours awake at the same time, though none of them is outside a 9-to-5 for both of you (in July: 8 hours shared, 4 hours free). Here are the good ones.
Sydney is 16 hours ahead of Toronto that week. On a weekday you are both awake for 8 hours, but none of them is outside work for both of you, so a lunch break or a commute has to do the work.
Worked out for the week of 11 January 2027 (11 Jan – 17 Jan), in Toronto time, with each zone’s own daylight-saving rules for those dates. Sydney awake 7 am – 11 pm, working 9 am – 5 pm weekdays; Toronto awake 7 am – 11 pm, working 9 am – 5 pm weekdays.

Stop doing the math every day
The Long Goodbye keeps your person’s local time and time of day on your home-screen widget and lock screen, so you can see whether it is morning coffee or midnight in Sydney before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.
What is the time difference between Sydney and Toronto?
Sydney is 14 to 16 hours ahead of Toronto, depending on the time of year. In 2027 it is 16 hours from 1 January to 13 March and from 7 November to 31 December; 15 hours from 14 March to 3 April and from 3 October to 6 November; 14 hours from 4 April to 2 October.
What is the best time to call Sydney from Toronto?
In January, the easiest two hours on a weekday are 8 – 10 pm Toronto, which is noon – 2 pm Sydney: Toronto evening, Sydney lunchtime, the next day there, during Sydney’s lunch break. At the weekend, Sat 6 – 9 pm Toronto (Sun 10 am – 1 pm Sydney) gives you a longer call. Change the awake and work hours in the finder on this page to fit your own days.
How many waking hours do Sydney and Toronto share?
If both of you are awake from 7 am to 11 pm, you share 8 hours on a January weekday, but none of them falls outside 9-to-5 working hours in both places; in July it is 8 hours shared and 4 hours free.
Does daylight saving time change the call times?
Yes. In 2027 Toronto changes its clocks on 14 March and 7 November and Sydney changes its clocks on 4 April and 3 October, so a call you keep at the same time in Toronto moves by an hour in Sydney on those dates. Check the table on this page and agree the new time out loud after each change.
