LibreOffice 7.6 Help

The following describes and lists some of the available add-in functions.

You will also find a description of the LibreOffice Calc add-in interface in the Help. In addition, important functions and their parameters are described in the Help for the Shared LibraryLibreOffice Calc add-in DLL.

LibreOffice contains examples for the add-in interface of LibreOffice Calc.

Calculates the number of days of the month in which the date entered occurs.

DAYSINMONTH(Datum)

Date is any date in the respective month of the desired year. The Date parameter must be a valid date according to the locale settings of LibreOffice.

=DAYSINMONTH(A1) vraća 29 dana ako A1 sadrži 1968-02-17, ispravan datum za veljaču 1968. godine.

ORG.OPENOFFICE.DAYSINMONTH

Calculates the number of days of the year in which the date entered occurs.

DAYSINYEAR(Datum)

Date is any date in the respective year. The Date parameter must be a valid date according to the locale settings of LibreOffice.

=DAYSINYEAR(A1) vraća 366 dana ako A1 sadrži 1968-02-29, ispravan datum za 1968. godinu.

ORG.OPENOFFICE.DAYSINYEAR

Determines whether a year is a leap year. If yes, the function will return the value 1 (TRUE); if not, it will return 0 (FALSE).

ISLEAPYEAR(Date)

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

=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.

Nikad ne koristite =ISLEAPYEAR(2/29/68), jer bi ovo prvo podijelilo 2 sa 29, pa rezultat sa 68, pa tek onda pozvalo funkciju ISLEAPYEAR koristeći ovaj mali broj kao serijsku oznaku datuma.

ORG.OPENOFFICE.ISLEAPYEAR

Calculates the difference in months between two dates.

MONTHS(StartDate; EndDate; Type)

StartDate is the first date

EndDate is the second date

Type calculates the type of difference. Possible values include 0 (interval) and 1 (in calendar months).

ORG.OPENOFFICE.MONTHS

Encrypts a character string by moving the characters 13 positions in the alphabet. After the letter Z, the alphabet begins again (Rotation). By applying the encryption function again to the resulting code, you can decrypt the text.

ROT13(Text)

Text is the character string to be encrypted. ROT13(ROT13(Text)) decrypts the code.

=ROT13("Gur Qbphzrag Sbhaqngvba jnf sbhaqrq va Frcgrzore 2010.") returns the string "The Document Foundation was founded in September 2010.". Notice how spaces, digits, and full stops are unaffected by ROT13.

ORG.OPENOFFICE.ROT13

Refer to the ROT13 wiki page for more details about this function.

Calculates the difference in weeks between two dates.

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.

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.

ORG.OPENOFFICE.WEEKS

Calculates the number of weeks of the year in which the date entered occurs. The number of weeks is defined as follows: a week that spans two years is added to the year in which most days of that week occur.

DAYSINYEAR(Datum)

Date is any date in the respective year. The Date parameter must be a valid date according to the locale settings of LibreOffice.

=DAYSINYEAR(A1) vraća 366 dana ako A1 sadrži 1968-02-29, ispravan datum za 1968. godinu.

ORG.OPENOFFICE.WEEKSINYEAR

Calculates the difference in years between two dates.

YEARS(StartDate; EndDate; Type)

StartDate is the first date

EndDate is the second date

Type calculates the type of difference. Possible values are 0 (interval) and 1 (in calendar years).

ORG.OPENOFFICE.YEARS

Add-ins can also be implemented through the LibreOffice API.
