This article will help you:
  • Schedule experiments to start and stop at specific time
  • Use Optimizely's Scheduler feature

Optimizely's scheduler lets you schedule your experiments or campaigns to start and stop them at specific times. You'll receive email notifications letting you know when the experiment has been started and stopped.

The scheduler uses GMT offset to calculate scheduling. Your local time will be shown so that you can account for the correct GMT offset.

Experiments can only be started or stopped on the hour. If you need to select more granular, arbitrary times, use our REST API instead. If you want to turn on an experiment or personalized experience only during certain times of day, use our audience conditions.

This feature is available with Enterprise plans
