Analysis Functions Part One

Analysis Functions Part Two

ESTASSUPERJARO

Komputas ĉu jaro estas superjaro. Se jes, la funkcio liveras la valoron 1 (TRUE); se ne, ĝi liveras je 0 (FALSE).

Sintakso

ISLEAPYEAR(Date)

Date specifies whether a given date falls within a leap year. The Date parameter must be a valid date.

Ekzemplo

=ISLEAPYEAR(A1) returns 1, if A1 contains 1968-02-29, the valid date 29th of February 1968 in your locale setting.

You may also use =ISLEAPYEAR(DATE(1968;2;29)) or =ISLEAPYEAR("1968-02-29") giving the date string in the ISO 8601 notation.

Never use =ISLEAPYEAR(2/29/68), because this would first evaluate 2 divided by 29 divided by 68, and then calculate the ISLEAPYEAR function from this small number as a serial date number.

SEMAJNOJ

Kalkulas la diferencon en semajnoj inter du datoj.

Sintakso

WEEKS(StartDate; EndDate; Type)

StartDate is the start date in the interval.

EndDate is the end date in the interval. The end date must be greater than the start date, or else an error is returned.

Type specifies the type of difference to be calculated. Possible values are 0 (time interval) or 1 (calendar weeks).

If Type = 0 the function will assume that 7 days is equivalent to one week without considering any specific day to mark the beginning of a week.

If Type = 1 the function will consider Monday to be the first day of the week. Therefore, except for the start date, each occurrence of a Monday in the interval is counted as an additional week.

This function considers Monday to be the first day of the week regardless of the current locale settings.

Ekzemplo

In the following examples, dates are passed as strings. However, they can also be stored in separate cells and be passed as references.

=WEEKS("01/12/2022","01/17/2022",0) returns 0 because Type was set to 0 and there are only 5 days in the interval.

=WEEKS("01/12/2022","01/19/2022",0) returns 1 because Type was set to 0 and there are 7 days in the interval.

=WEEKS("01/12/2022","01/17/2022",1) returns 1 because Type was set to 1 and the interval contains a Monday, since 01/12/2022 is a Wednesday and 01/17/2022 is a Monday.

=WEEKS("01/10/2022","01/15/2022",1) returns 0 because Type was set to 1 and the interval does not contain any Mondays, except for the start date.
