# Schedule experiment stop — Amplitude Changelog

You can now schedule when an experiment or flag stops, not just when it starts. Set a start time, an end time, or both. At the end time, delivery stops, the analysis window freezes, and the experiment moves to Completed (Pending decision).

# Schedule experiment stop

You can now schedule when an experiment or flag stops, not just when it starts. Set a start time, an end time, or both. At the end time, delivery stops, the analysis window freezes, and the experiment moves to Completed (Pending decision).

## What it is

**Description:** You can now schedule when an experiment or flag *stops*, not just when it starts. Set a start time, an end time, or both. At the end time, delivery stops, the analysis window freezes, and the experiment moves to **`Completed (Pending decision)`**.

*What's included:* • *Start and end in one modal* — check `Start time`, `End time`, or both; a `Runs 14 days` summary confirms the window before you commit • *Auto-stop at the end time* — experiments stop delivering variants, flags turn off • *Analysis window freezes at the scheduled stop*, so results don't keep extending past the intended end • *Status moves to Completed (Pending decision)* and the active-experiment quota slot is released for the next test • *Owners get notified* when a scheduled start or stop fires • *Schedule details in the status pill tooltip* — see exactly when it starts and stops

**Why:** Teams had to stop experiments by hand. Miss the window and variants keep shipping past the planned end — stretching analysis and holding an active-experiment slot. Time-boxed tests now end on schedule.

**Where:** Experiment or flag page → *Start Experiment* → *Schedule*. Once running, use *Edit schedule*.

**Available in EUDC:** Yes

**When:** Now!
