SO TIME - What if a day had 36 hours?

What if a day had 36 hours? SO TIME is an experimental clock that reimagines the 24-hour day. It runs at 1.5× speed, turning one ordinary 24-hour day into 36 SO TIME hours. 27:18. 31:42. 35:59. It doesn’t give you more time. It changes how time feels. This is not a productivity hack. It’s a small experiment in questioning one assumption we rarely question: Why 24 hours? SO TIME is available for $1/month. TIME IS NEGOTIABLE.
