Hi, I would want to use this calendar as an online resource that could then export multiple events in plain text format, filtered by selected dates, so we can use it in a newspaper. Is there something like that built in or would it be easy to customize?
There is not something like that built in. It may be possible to customize, but I can’t really comment on how easy that would be. I recommend that you download our free core plugin, The Events Calendar, and experiment with customizing that. As the core plugin provides the base for the PRO add-on, what works in core will likely be applicable to PRO as well. That way you can experiment with customization without a purchase.
