Events: congress, workshop, conference, seminar, hackthon[edit]

required values for properties:

?dateModified
?start_time
?end_time

Note that if the following statement is placed outside the UNION the query takes far too long, hence keeping it within each UNION block

    ?item schema:dateModified ?dateModified;
    wdt:P580 ?start_time;
    wdt:P582 ?end_time .
