• Notice that the strings on the left side of the '=' have spaces escaped with the '\' character. This is needed so do not remove that. The escape character is not needed on the right side of the '='. The above example has "First\ Name" on the left and "Primero Nombre" on the right.
• If you have a label that contains a colon, it must be escaped in the default translation file. Newly downloaded default translation files properly escape a colon with a '\'. Translation files with strings containing colons will have to be re-uploaded with the colon properly escaped.

Date, Time, and Date/Time controls are locale-aware for both parsing and format. When the Automatic format is selected, both date and time entry and display formatting will be locale-specific. The designer has the option to set a particular date or time format independent of the locale by using the date format or time format property, but this is not recommended because it is not responsive to user locale.

Here is an image of Date/Time controls with the browser language set for German and the Date/Time controls set for Automatic. Notice the date format is DD.MM.YYYY and the time format is HH:MM:

Changing the Firefox browser language setting to Lithuanian displays the dates and times using the format YYYY-MM-DD and HH:MM respectively:

The automatic locale-specific formatting and parsing for date, time, and date/time controls can be configured by manually adding the following properties in the locale properties file:

For example, let's say you want to change the MM.DD.YYYY to display as "Day of the week, Month Day, year" in the German locale. Simply add the following to the ger locale file located in the WEB-INF/data/locale directory as explained ServerCustomization above:

frevvo.date.format="EEE, MMM d, ''yy"

After replacing the /WEB-INF/data directory file with the updated one, the date will display as shown in the Firefox browser set for the German locale:

Date Picker

The Date picker will be automatically translated according to the browser locale. You can override the browser setting by adding the properties shown below to the locale file. This localization only applies to the date picker on the desktop as the native date picker will be shown on mobile devices. You can translate  (locale-specific) month names and abbreviated day of week names (two characters).  The days of the week will always be shown as Sunday through Saturday, left to right on the date picker.  Only the Gregorian calendar system is supported.

To localize the date picker on the desktop, manually add the following properties in the appropriate locale properties file in the WEB-INF/data/locale directory as explained ServerCustomization.

For example, Let's say you add the properties below to a Chinese translation file named zh:

frevvo.date.month.1=JaC
frevvo.date.month.2=FeC
frevvo.date.month.3=MaC
frevvo.date.month.4=ApC
frevvo.date.weekday.1=Mc
frevvo.date.weekday.2=Tc
frevvo.date.weekday.3=Wc
frevvo.date.weekday.4=Tc  

After replacing the modified /WEB-INF/data directory file, restarting frevvo and setting the Firefox browser to Chinese - zh, the date picker will display as shown in the image:

Notice the month is displayed as JaC and the days of the week show Mc, Tc, Wc and Tc for Sunday - Wednesday as specified by the format properties we added to the locale file. Thursday, Friday, and Saturday display in Chinese - the language setting of the browser in this example. 

Entries for the Today and Close buttons on the Date Picker are already included in the default locale file so all you need to do is add your translations for them in the locale file you are going to use. 

Internationalization of Date Picker for iOS.

The locale of the date picker on the safari browser changes with the iPhone/iPad's "Region Format" settings, not the language settings. After setting the language in iOS, set the appropriate country/region format in the iPhone general settings.

Navigate these settings to change the Country/Region Format on iOS devices: General>International>Region Format: Select the Appropriate Country.
