# Workflow Automation: Trigger By Day or Date

Flows triggered **By Date or Day** are run on specific dates or days and have no initial *App* context since they are not triggered by any *Podio* data.

![Trigger By Day Date 1](https://www.progress.com/podio/documentation/assets/adf1a4b65a592d41ec656a06cdf8a3af/daydate1.png)

Flows created in this area, are scheduled to run every night at midnight in your *Time Zone*, unless otherwise selected from the time drop-down menu.

*Please note these flows are processed in order of previously recorded run time.This prevents long and slow running flows from affecting other users. Refer to your [**Throttled Apps and Webhooks**](https://www.progress.com/podio/documentation/workflow-automation/throttling-webhooks) link on your Account Settings page.*

> *The [**Date Match**](https://www.progress.com/podio/documentation/workflow-automation/filters-and-conditions/date-match) filter is automatically selected at the time of flow creation. Use this to select when the flow should run and how often.*

This filter is not mandatory and can be removed to run on a daily/hourly basis.

Since this type of flow is not attached to an *App*, a [**Collector**](https://www.progress.com/podio/documentation/workflow-automation/getting-started/using-collectors-logic-and-actions) is required to access *Items* and respective *fields*.
