# Show Booking Times in 12-Hour or 24-Hour Format

Choose how a calendar ending shows times to your leads: 12-hour (2:30 PM), 24-hour (14:30), or Auto, which follows each visitor's browser language.

Calendar endings show booking times like 2:30 PM by default. If your leads are used to a 24-hour clock, you can show 14:30 instead, or let each visitor's browser decide. Each calendar ending has its own setting, so two calendars in the same form can use different formats. New to endings? See [Endings Explained: Thank-You, Redirect, and Calendar](https://help.roasform.com/en/articles/29-endings-explained-thank-you-redirect-and-calendar.md).

## How to change it

1.  Open your form in the form builder.
    
2.  In the **Endings** section at the bottom left, click your Calendar ending. Its settings appear in the right-side panel.
    
3.  Click **Calendar Settings**.
    
4.  Under **Time format**, right below **Calendar**, pick one of the three options.
    
5.  Click **Save**.

-   **12-hour (2:30 PM):** the default. Every calendar ending starts here, so your existing forms don't change until you pick something else.
    
-   **24-hour (14:30):** times run from 00:00 to 23:59 with no AM or PM. Half past midnight shows as 00:30.
    
-   **Auto (visitor's browser language):** each visitor sees the clock that is usual for their browser's language. More on this below.
    

The builder preview updates as soon as you click Save. When you create a new Calendar ending, the same window opens, so you can pick the format right away.

## Where your leads see it

-   **The calendar:** the time slots, and the current time next to the timezone picker.
    
-   **The booking confirmed screen:** the date and time card a lead sees after booking.
    
-   **The Reschedule and Cancel pages:** the meeting time at the top, and the message after a lead moves their meeting.
    

It works the same on every form skin, on phones and on desktop, for both [GoHighLevel](https://help.roasform.com/en/articles/13-gohighlevel-calendar-integration.md) and [Calendly](https://help.roasform.com/en/articles/12-calendly-calendar-integration.md) calendars.

## How Auto decides

Browsers don't tell websites whether a phone or computer is set to a 12-hour or 24-hour clock. Auto follows the visitor's browser language instead. A browser set to US English shows 2:30 PM, while UK English, German and French show 14:30.

> **Tip:** In the builder, Auto previews with your own browser's language, so some of your leads may see the other format.

## Good to know

-   **Times follow the visitor's timezone:** the calendar shows times in the lead's own timezone, and they can change it with the timezone picker. The time format stays the same when they do.
    
-   **Emails and calendar invites:** confirmation emails and calendar invites come from GoHighLevel, Calendly or the lead's own calendar app, which use their own time settings.
