To sort the list of holidays currently displayed in the Holidays Explorer, simply click on the column header corresponding to the sorting criterion you want to use. A small arrow appears in the headeer of the sorting column to indicate if the current sort order is ascending or descending.
You can sort on more than one column at the time, by holding the SHIFT key while clicking on column headers. In the example below, the list is sorted according to the type of recurrence of each holiday, and by the date of its occurrences, ascending on the left and descending on the right.
Another and more powerful way of performing sorts based on multiple criteria is to use grouping.
