Countdown transmission times

Countdown is currently broadcast by Channel 4 from 14:10 to 15:00 British Time on Mondays to Fridays most weeks throughout the year. In addition to the +1 channel, most programmes are repeated early mornings on Channel 4 at around 06:00, about 32 hours after their first transmission.

Countdown programmes used to have additional repeat showings on More4 and 4seven, but these practices have now stopped.

They were also given a showing on S4C a few days after the first Channel 4 transmission, but this ended with the completion of the digital switchover in Wales in March 2010 (at which point S4C ceased broadcast of Channel 4 programmes, since Channel 4 is now available throughout Wales).

Programmes can, however, be watched using All4, Channel 4's on-demand service, at any time up to thirty days after the first transmission.
