Given an ISO 8601 week number, get date of first day of that week in LibreOffice Calc spreadsheet

阅读更多关于 Given an ISO 8601 week number, get date of first day of that week in LibreOffice Calc spreadsheet

问题 LibreOffice Calc spreadsheet offers a function ISOWEEKNUM to return the standard ISO 8601 week number of the specified date. I want the opposite. ➠ Given a standard week number, give me the date of the first day of that week (the Monday date). Passing integers is acceptable. Also nice if able to pass a string in standard format. Like this: DATE_OF_ISOWEEKNUM( 2017 , 42 ) ➝ date of Monday of week 42 in week-based year 2017 DATE_OF_ISOWEEKNUM( "2017-W42" ) ➝ date of Monday of week 42 in week
