Info

title	Calendar and timezones

Keep in mind that all dates are interpreted using the (proleptic) Gregorian calendar rules.

The timezone used in these type of functions is the system default timezone of the server that hosts the Blueriq runtime where the function is executed.

Info

title	Date and time formats

The way in which date and time values are displayed in the user interface is determined by the date display formats, which can be configured per language code.
For example the Dutch nl-NL date format could be configured as "dd-MM-yyyy", whereas the English en-US date format can be defined as "MM/dd/yyyy". More information about language specific formats can be found in Reference Guide: Language Formats

For example, January 1, 1998 was a Thursday. Then week 1 of 1998 starts on December 29, 1997, and ends on January 4, 1998. If, however, the first day of the week is defined as Sunday (as is the case in the US), then week 1 of 1998 starts on January 4, 1998, and ends on January 10, 1998; the first three days of 1998 then are part of week 53 of 1997.
