Optimize's experiment scheduling feature allows you to set your experiment's start and end times so that they work best with your business objectives. Use it to schedule your experiment to coincide with an important event – for example, during a campaign or over a holiday – or to any time that better fits your schedule.In this article:
The following permissions are required to schedule Optimize experiments:
|Edit schedule (draft experiment)||–||Y||Y|

In this example, we'll schedule an experiment to run for two weeks in April. You should run your experiment for a minimum of two weeks to account for cyclical variations in web traffic.

STEP 1 – Click CREATE SCHEDULE
STEP 2 – Select a start time.
STEP 3 – Select an end time.
STEP 4 – Click DONE.

STEP 6 – Click SAVE.
STEP 7 – Click START EXPERIMENT.
STEP 8 – Click START.

After starting a scheduled experiment, it can be edited or canceled, but it can't be ended.
To edit or cancel a scheduled experiment, click More  on the right of the experiment status, then:
- Edit schedule – to change the start and/or end time(s).

You can reuse an ended experiment by copying it.

To end an experiment, click END EXPERIMENT in the experiment status bar.
To monitor a running experiment or see the results of a concluded experiment, click the Reporting tab at the top of the experiment detail page. The report is broken down into a series of cards that contain data about your experiment, including its status and how your variants perform against your objectives.
