11.07.2021 is a sunday. There are different week numbering systems in the world which have different first day of week definition. For example in the EU the first day of the week is monday while in the US / Canada it is sunday. That is reflected in locales and thus you are seeing that behaviour.
See: https://en.wikipedia.org/wiki/Week#Other_Week_Numbering_Systems In GWT you can see locale settings here (see property firstDayOfTheWeek which contains an index of the content of property weekdays): Generic German (Monday): https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/i18n/client/constants/DateTimeConstantsImpl_de.properties Generic English (Sunday): https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/i18n/client/constants/DateTimeConstantsImpl_en.properties English - Great Britain (Monday): https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/i18n/client/constants/DateTimeConstantsImpl_en_GB.properties So with locales it is important to pick the right country as well if possible instead of just the language. -- J.
