# Schedule timezone

> Set the timezone that controls when pulse schedules fire across your Chartcastr organization. Defaults to auto-detected timezone or UTC.

## Overview

The Schedule Timezone setting determines how all pulse schedule times are interpreted. For example, if you set your schedule to "9 AM daily" and your timezone is set to `America/New_York`, pulses will fire at 9 AM Eastern Time.

## Default

When your organisation is first created, Chartcastr will try its best to discover your preferred timezone automatically. We recommend double-checking that it was detected correctly in your [Organisation Settings](/admin/settings). If we couldn't determine it, schedules will default to **UTC**.

## Configuration

<Note>
  **Organization Setting**: This configuration is applied across your entire organization and affects all connections and team members.

  Change Schedule Timezone
</Button>

1. Go to [Settings → Organisation Settings](https://chartcastr.com/admin/settings).
2. Locate the **Schedule Timezone** section.
3. Search for and select your desired timezone (e.g., `America/New_York`, `Europe/London`).

The change takes effect immediately for all future scheduled pulses.

## Impact

This setting affects:

* When scheduled pulses fire (e.g. "9 AM daily" is interpreted in the selected timezone).
* All connections across the organisation use the same timezone.
* Existing schedules are not modified — only the timezone interpretation changes.
