Hello Rens,
Thanks for reaching out with your question.
By default, the tickets of events do not show up on the shop page, thus you will not be able to filter them.
With some custom coding it could be done that they show up, and if the name or the description of the ticket (not the event!) contains the date, then you could possible do a freetext search / filter on them.
Otherwise, if you use <span class=”paragraph”>The Events Calendar</span> plugin as well, not only <span class=”paragraph”>Event Tickets</span> / <span class=”paragraph”>Event Tickets Plus</span>, you get different calendar views like month view or week view, where you can see the different events.
I hope this helps. Please, let me know if you have more questions.
Cheers,
Andras
