Understanding internal localization in the Guesty Booking Engine

The Guesty Booking Engine includes several smart localization features that work behind the scenes to optimize the booking experience for your guests.

Calendar regional preferences

The booking calendar automatically adjusts its first day based on your selected language:

  • Sunday start: US English and other markets where Sunday begins the week
  • Monday start: European languages and regions following ISO standards

This small detail makes a big difference in user experience, as guests can navigate dates using the calendar format they're accustomed to.

Currency formatting

Currency displays match regional conventions, ensuring prices look familiar to your international guests, for example:

Language/Region

USD Format

EUR Format

Local Currency

English (US) $123,456.79 €123,456.79 $123,456.79 (USD)
Spanish (Spain) 123.456,79 US$ 123.456,79 € 123.456,79 € (EUR)
Polish 123 456,79 USD 123 456,79 € 123 456,79 zł (PLN)

The system also handles currencies without decimal places (like Japanese Yen) by applying appropriate rounding rules.

Date formats adapt to language settings

Check-in and check-out dates, cancellation policies, and other date information automatically displays according to regional formats. This includes proper 12-hour vs. 24-hour clock formatting and date ordering that matches local expectations.
