How Far Ahead Can The Upcoming Events Widget Display?

Hi All, I hope this isn't just something easy I have missed, but I have an issue where upcoming events that happen in the far future, say 3 months, are not making it to the Upcoming Events widget.

I did a bit of trouble shooting and day by day changed the start date closer today's date, and strangely enough, when I got with 36 day of the current date, it showed up! Seems super arbitrary to me.

Is there a date range which the widget is set to? Is there a way to change it?
