Question 1

How do I find a time that works for multiple time zones?

Accepted Answer

Add each participant and set their working hours. The tool checks every 15-minute UTC slot of the day and finds the longest contiguous window where everyone is still inside their working hours. If that window is 0 there's no shared time at all — someone has to work out of hours or you split into two calls.

Question 2

Which Australian states observe Daylight Saving Time?

Accepted Answer

Queensland, Western Australia and the Northern Territory do NOT observe DST. New South Wales, Victoria, Tasmania, the ACT and South Australia do — clocks go forward on the first Sunday of October and back on the first Sunday of April. That means Sydney is 1 hour ahead of Brisbane from October to April, and Perth is 2 hours behind the east coast in winter but 3 hours behind in summer.

Question 3

Why does Darwin have a +9:30 offset?

Accepted Answer

Darwin (and the rest of the Northern Territory) uses Australian Central Standard Time — UTC+9:30 — and doesn't observe DST. Adelaide and the rest of South Australia use the same +9:30 base but do observe DST, shifting to ACDT (UTC+10:30) in summer. The overlap grid handles the half-hour offset correctly.

Question 4

Does it handle half-hour and quarter-hour offsets?

Accepted Answer

Yes. India (+5:30), Iran (+3:30), Afghanistan (+4:30), Myanmar (+6:30), Newfoundland (−3:30), Darwin (+9:30), Adelaide (+9:30/+10:30), Nepal (+5:45) and the Chatham Islands (+12:45) all render on the grid correctly. The internal algorithm steps every 15 minutes, not every hour, so these don't drift.

Question 5

Can I share the overlap view with my team?

Accepted Answer

Yes — hit Share and the URL contains everyone's zones and working hours. Paste it into Slack, email or Teams and recipients open the same view. The preview card shows the shared-window summary so people can scan the trade-off before clicking.

Question 6

Is this tool free to use?
