A check-in date that reads "2025-07-19" to a German guest and "19 Jul 2025" to an English one is the difference between a message that feels written for someone and one that feels generated. Bookboost uses Twig, so any date or time token can be reformatted, including into the guest's own language.

Insert the date token you want using the Token button in the editor, then add a formatting filter after a pipe character inside the same braces.

So a token that arrives as:

{{ your_date_token }}

becomes:

{{ your_date_token|date('d M Y') }}

Everything below is the part after the pipe. The token itself always comes from the Token button, so you never need to type it by hand.

Use this for compact displays, such as a summary line or anything a guest will read on a phone.

{{ your_date_token|date('d M Y') }}

Output:

Use format_date with a locale when you want the weekday and month spelled out, in the right language.

English:

{{ your_date_token|format_date('full', locale='en') }}

Output:

Dutch:

{{ your_date_token|format_date('full', locale='nl') }}

Output:

Swap the locale code for any language you send in, for example de, fr, es, or sv.

Use format_time with one of four presets.

{{ your_time_token|format_time('short') }}

For a time of 10:30 UTC, the four presets give:

Short is almost always the one you want in a guest message. The others include seconds, and full spells out the time zone.

Use format_datetime, which takes a date format and a time format, then the locale.

{{ your_datetime_token|format_datetime('short', 'short', locale='de') }}
