This page converts an organiser's published start time into the Australian time zone you choose. No event rows are filled in this edition: each date and time reads Not confirmed on 2026-11-13, because the organiser schedules are not yet read. The conversion rules and six worked examples below are complete and can be checked by hand.

## Choose a time zone

Select a zone, and the calendar lists each event in that zone, next to the organiser's own local time. It lists dates only: no odds, no prices, no bets.

The same logic is written out below as a static table, so the page works without scripts.

**Where this stands:** the converter is ready; the event rows wait for the organisers' pages.

## Offsets used for the conversion

Each zone has a standard offset from UTC. Three of the seven zones do not move their clocks in summer.

**Australian time zones · IANA tz database · checked 2026-11-13**

| Zone (IANA id) | Standard time | Daylight time | Moves clocks |
|---|---|---|---|
| Sydney (Australia/Sydney) | AEST, UTC+10 | AEDT, UTC+11 | Yes |
| Melbourne (Australia/Melbourne) | AEST, UTC+10 | AEDT, UTC+11 | Yes |
| Hobart (Australia/Hobart) | AEST, UTC+10 | AEDT, UTC+11 | Yes |
| Brisbane (Australia/Brisbane) | AEST, UTC+10 | None | No |
| Adelaide (Australia/Adelaide) | ACST, UTC+9:30 | ACDT, UTC+10:30 | Yes |
| Darwin (Australia/Darwin) | ACST, UTC+9:30 | None | No |
| Perth (Australia/Perth) | AWST, UTC+8 | None | No |

**Where this stands:** offsets are read from the IANA database at conversion time, not typed in by hand.

## The conversion rule

Two steps turn an organiser's local time into yours.

1. Subtract the organiser zone's offset on that date to get the start in UTC.
2. Add the offset of your chosen zone on the same date.

If the result crosses midnight, the date moves with it. The offset is taken for the event's date, not for today's.

**Where this stands:** one rule, applied per date, so a summer event and a winter event can differ.

## Six worked examples

Each row converts noon in Melbourne. Melbourne is on AEDT (UTC+11) in the summer column and on AEST (UTC+10) in the winter column.

**Illustrative example, not an event or a price · noon in Melbourne · checked 2026-11-13**

| Target zone | Summer offset | Noon Melbourne in summer | Winter offset | Noon Melbourne in winter |
|---|---|---|---|---|
| Sydney | UTC+11 | 12:00 | UTC+10 | 12:00 |
| Hobart | UTC+11 | 12:00 | UTC+10 | 12:00 |
| Brisbane | UTC+10 | 11:00 | UTC+10 | 12:00 |
| Adelaide | UTC+10:30 | 11:30 | UTC+9:30 | 11:30 |
| Darwin | UTC+9:30 | 10:30 | UTC+9:30 | 11:30 |
| Perth | UTC+8 | 09:00 | UTC+8 | 10:00 |

Worked line for Perth in summer: 12:00 AEDT is 01:00 UTC; adding 8 hours gives 09:00 AWST.

**Where this stands:** the gap between Melbourne and Perth is 3 hours in summer and 2 hours in winter.

## Event rows and their sources

A row is published only after the organiser's own page has been read. It then carries the page address, the local start time as published and the date it was read.

**Event schedule · organiser pages · checked 2026-11-13**

| Organiser | Event | Start (organiser local time) | Status |
|---|---|---|---|
| Tennis Australia | Australian Open 2027 | Not confirmed on 2026-11-13 | Organiser page not yet read |
| AFL | Season fixtures | Not confirmed on 2026-11-13 | Organiser page not yet read |
| NRL | Season fixtures | Not confirmed on 2026-11-13 | Organiser page not yet read |
| Racing Victoria | Race meetings | Not confirmed on 2026-11-13 | Organiser page not yet read |
| Cricket Australia | Match schedule | Not confirmed on 2026-11-13 | Organiser page not yet read |

Event rows are re-read every 7 days in the 8 weeks before an event. See [how data is refreshed](https://bookiechecklist.com/how-we-source-and-update-data/).

**Where this stands:** no event date is stated until its organiser's page has been read.

## FAQ

**Which time zones does the calendar cover?**

Seven IANA zones: Australia/Sydney, Melbourne, Hobart, Brisbane, Adelaide, Darwin and Perth. Pick one in the Time zone field and every start time is shown in that zone.

**Why do the event rows read Not confirmed on 2026-11-13?**

The organiser schedules are not yet read for this edition. A row is filled only when the organiser's own page has been read, with its address and the date it was read.

**How often are event dates re-checked?**

Event rows have a time-to-live of 7 days and are re-read weekly for the 8 weeks before an event. An older row is marked Not confirmed rather than left on the page.

**Does the calendar show odds or prices?**

No. It lists dates and start times only. There are no odds, prices or bets on this page.

**Why is Adelaide always 30 minutes behind Melbourne?**

Both observe daylight saving, but Adelaide's standard offset is UTC+9:30 and Melbourne's is UTC+10. The gap holds in summer (UTC+10:30 against UTC+11) and in winter.
