note

These values apply only to the standard date format that you select under - LibreOffice Calc - Calculate.


note

При вводе дат как части формул, косые черты или тире, используемые в качестве разделителей дат, интерпретируются как арифметические операторы. Поэтому даты, введенные в этом формате, не распознаются как даты и приводят к ошибочным вычислениям. Чтобы даты не интерпретировались как части формул, используйте функцию DATE, например DATE (1954;7;20) или поместите дату в кавычки и используйте нотацию ISO 8601, например "1954-07-20". Избегайте использования форматов даты, зависящих от локальных настроек, таких как "07/20/54", расчёт может привести к ошибкам, если документ загружен в соответствии с иными локальными настройками.


tip

Unambiguous conversion is possible for ISO 8601 dates and times in their extended formats with separators. If a #VALUE! error occurs, then unselect Generate #VALUE! error in - LibreOffice Calc - Formula, button Details... in section "Detailed Calculation Settings", Conversion from text to number list box.


Example

=WEEKDAY("2000-06-14") returns 4 (the Type parameter is missing, therefore the standard count is used. The standard count starts with Sunday as day number 1. June 14, 2000 was a Wednesday and therefore day number 4).

=WEEKDAY("1996-07-24";2) returns 3 (the Type parameter is 2, therefore Monday is day number 1. July 24, 1996 was a Wednesday and therefore day number 3).

=WEEKDAY("1996-07-24";1) returns 4 (the Type parameter is 1, therefore Sunday is day number 1. July 24, 1996 was a Wednesday and therefore day number 4).

=WEEKDAY("2017-05-02";14) returns 6 (the Type parameter is 14, therefore Thursday is day number 1. May 2, 2017 was a Tuesday and therefore day number 6)

=WEEKDAY(NOW()) returns the number of the current day.

tip

To obtain a function indicating whether a day in A1 is a business day, use the IF and WEEKDAY functions as follows:
IF(WEEKDAY(A1;2)<6;"Business day";"Weekend")
