Why people convert Sydney to PET time

Scheduling a call from Sydney to PET: a 10:00 AM start in Sydney lands at 7:00 PM in PET the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -15h gap: Sydney and PET have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PET is 6:00 PM in Sydney.
Coordinating a Sydney-based team with PET contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM AEST" is unambiguous; "3 PM" across a -15h gap is not.
With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week Sydney takes the early slot, the next week PET does.
Sydney: Clocks spring forward on Sat, Oct 3, 2026. Re-check this page after that date because the offset changes and so does the -15h gap.
