# Update Lead Timezone (Vapi)

> Automatically update the lead timezone before placing a call.

Use **Update Lead Timezone** to automatically detect and update the timezone for a lead based on their phone number.

This ensures that your calling window logic works correctly and that you do not call leads outside of appropriate hours.

## Step 1. Add the action

Add **Update Lead Timezone** as an action in your workflow before the **Place Call** or **Wait Until Calling Window** action.

## Step 2. Save the action

No additional configuration is needed. Sympana Connector will use the lead phone number to determine the timezone and update the contact record.

## When to use this action

Use **Update Lead Timezone** when:

* You are calling leads across multiple timezones
* You want to ensure calling window compliance
* Your lead records do not already have timezone data

## Best practice

Place this action early in your workflow, before any time-based logic like **Wait Until Calling Window**.
