날짜 값 변환

다음의 함수는 날짜 값을 계산 가능한 숫자로 또는 그 반대로 변환합니다.

DateSerial Function

지정한 연도, 월 또는 일의 Date 값을 구합니다.

DateValue Function

날짜 문자열에서 날짜 값을 반환합니다. 날짜 문자열은 단일 숫자 값의 완전한 날짜입니다. 또한 이 일련 번호를 사용하여 두 날짜의 차를 확인할 수 있습니다.

Day Function

DateSerial 또는 DateValue가 생성한 연속 날짜 번호에 기초하여 날짜를 나타내는 값을 구합니다.

Month Function

DateSerial 또는 DateValue 함수를 사용하여 생성한 연속 날짜에서 월을 구합니다.

WeekDay Function

This function returns the number corresponding to the weekday represented by a serial date number that is generated by the DateSerial or the DateValue functions.

Year Function

DateSerial 또는 DateValue 함수를 사용하여 생성한 연속 날짜 번호에서 연도를 구합니다.

CDateToIso Function

Returns the date in ISO format without separators (YYYYMMDD) from a serial date number that is generated by the DateSerial or the DateValue or the CDateFromIso function.

The year part consists of at least four digits, with leading zeros if the absolute value is less than 1000, it can be negative with a leading minus sign if the date passed denotes a year before the common era (BCE) and it can have more than four digits if the absolute value is greater than 9999. The formatted string returned can be in the range "-327680101" to "327671231".

참고 아이콘

Years less than 100 and greater than 9999 are supported since LibreOffice 5.4.


CDateFromIso Function

Returns the internal date number from a string that contains a date in ISO format (YYYYMMDD or YYYY-MM-DD).

The year part must consist of either two (supported only in YYMMDD format without separators for compatibility) or at least four digits. With four digits leading zeros must be given if the absolute value is less than 1000, it can be negative with a leading minus sign if the date passed denotes a year before the common era (BCE) and it can have more than four digits if the absolute value is greater than 9999. The formatted string can be in the range "-327680101" to "327671231", or "-32768-01-01" to "32767-12-31".

An invalid date results in an error. Year 0 is not accepted, the last day BCE is -0001-12-31 and the next day CE is 0001-01-01. Dates before 1582-10-15 are in the proleptic Gregorian calendar.

팁 아이콘

When converting a date serial number to a printable string, for example for the Print or MsgBox command, the locale's default calendar is used and at that 1582-10-15 cutover date may switch to the Julian calendar, which can result in a different date being displayed than expected. Use the CDateToIso Function to convert such date number to a string representation in the proleptic Gregorian calendar.

The YYYY-MM-DD format with separators is supported since LibreOffice 5.3.4. Years less than 100 or greater than 9999 are accepted since LibreOffice 5.4 if not in VBA compatibility mode.


CDateToUnoDate Function

Returns the date as a UNO com.sun.star.util.Date struct.

CDateFromUnoDate Function

Converts a UNO com.sun.star.util.Date struct to a Date value.

CDateToUnoDateTime Function

Returns the time part of the date as a UNO com.sun.star.util.DateTime struct.

CDateFromUnoDateTime Function

Converts a UNO com.sun.star.util.DateTime struct to a Date value.

DateAdd Function

Adds a date or time interval to a given date a number of times and returns the resulting date.

DateDiff Function

Returns the number of date or time intervals between two given date values.

DatePart Function

DatePart 함수는 날짜의 특정 부분을 반환합니다.
