The best time for a call
If both sides keep roughly 9-to-5 hours, you get 1 hour hour of overlap on a normal weekday: 4:00 PM to 5:00 PM in Los Angeles, which is 9:00 AM to 10:00 AM in Sydney.
When the gap is 19 hours, the overlap grows to 3 hours: 2:00 PM to 5:00 PM in Los Angeles.
When the gap is 18 hours, the overlap grows to 2 hours: 3:00 PM to 5:00 PM in Los Angeles.
Sydney is between 17 and 19 hours ahead of Los Angeles depending on the season, which is easier to picture as “tomorrow, and five to seven hours earlier on the clock.”
The West Coast afternoon is Sydney’s morning, which makes this one of the friendlier long-haul pairs: a 3 or 4 p.m. call in Los Angeles reaches Sydney in its early-to-mid morning the next day. The awkward day is Friday, when Los Angeles afternoons fall on a Sydney Saturday.

Why the time difference changes
Los Angeles and Sydney sit in different hemispheres, so their summers, and their daylight saving seasons, fall at opposite ends of the calendar. Los Angeles: clocks go forward on the second Sunday in March and back on the first Sunday in November. Sydney: clocks go forward on the first Sunday in October and back on the first Sunday in April.
Each of those four changes moves the gap by an hour, which is why it drifts across a two-hour range during the year.
