> For the function {{WeekOfYear}}, we explicitly set the first day of the week to {{Calendar.MONDAY}}. However, {{FromUnixTime}} does not explicitly set it. So, we are using the default first day of the week based on the locale setting (see https://docs.oracle.com/javase/8/docs/api/java/util/Calendar.html#setFirstDayOfWeek-int-). 
> Let's do a survey on what other databases do and make the setting consistent.
