# Automation Duration

When you schedule automations in Automation Studio, make sure that the duration and schedule are aligned to prevent system stability issues.

To ensure system stability, automations that run for more than 24 hours automatically stop when the next scheduled occurrence begins. Check the expected duration before you schedule automations that run for more than 24 hours.

![Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_journeys_and_automations-264-0-0-production-enus/e08cdd71-c1c1-4ae5-a5e9-8a6dad583ad4/images/icon_example.png)

Example

- You schedule a daily automation to run for 36 hours. When the next instance starts, the previous automation stops and produces no more data.
- You schedule a weekly automation to run for 36 hours. Because it only runs new instances every 2 days, this automation isn’t stopped because there’s enough time between occurrences.
