| The NOW function returns a date- and timestamp. It is only recalculated when the expression in which you use the NOW function is reevaluated. This recalculation will not cause other expressions that use the NOW function to be reevaluated. |
WEEKNUMBER
WEEKNUMBER returns the week number within the year of a given date or dateTime value. The week number is returned as an integer in the range 1 - 53. Week 1 for a year is the earliest seven day period starting at the first day of the week that contains at least x days from that year. The first day of the week and the minimal days in that first week are defined by the region settings. In most cases the first day of the week is Monday and the minimal days in the first week is 4 (these are the values reflecting ISO 8601 and many national standards).
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.
