DateFinder is a GAS library for searching the date objects from the cell range on the sheet in the Spreadsheet and retrieving the searched range as the RangeList object using Google Apps Script (GAS).
There is the Class TextFinder for searching the text from cells of the Spreadsheet using the Google Apps Script. But in this case, the date object in the cell is used as the string. Namely, the values for searching are used as the same with the values retrieved by
getDisplayValues(). So for example, when there are the date objects in the cells with the various formats, the date cannot be searched by the Class TextFinder. So I created this library. When this library is used, the date objects in the cells can be retrieved by the date object and/or the range between 2 dates.
