Hello,
Please provide more details about the error you have with "Edge".
And you should also check your browser javascript console in order to see if you do not have any JS error which would break the rest of the JS in the page, including the advanced date picker.
The advanced date picker is a plugin but it's using the JQuery UI calendar. That JS library is provided directly by the JQuery team and has been tested and validated for a lot of browsers, including Edge.
