The triple j Hottest 100 countdown usually runs for most of the afternoon, roughly around eight hours from the first song to number one.

Rough duration

  • Listeners on fan forums report that the full Hottest 100 broadcast is “normally about 8 hours” including tracks, host chat, interviews and hype segments.
  • The countdown typically starts at 12 pm (noon) AEDT on the day and runs through into the evening until the number 1 is revealed.

What that means in practice

  • If you tune in from the very start, expect to be listening from lunchtime until early evening if you want to hear #1 live.
  • The exact finish time can shift a bit year to year depending on how much commentary, interviews and other segments they include, but planning for about eight hours is a safe bet.
