It’s been a while! But a tip: if the dates have been saved by a date_picker field and not a date_time_picker field in Ymd format (for example 20200916), you’ll need to convert the values in the database to a machine-legible date string (Y-m-d) before integrating this solution. Otherwise, the dates will all be displayed as 1970 dates, and potentially saved with incorrect values when re-edited.
