If you are using the mobile app, you can search by date range. Here's how:
1. Click the magnifying glass at the bottom.
2. Click on the Search Bar.
3. Right below the Search Bar click the "All Dates" tab
4. Click "Choose a Date Range" at the bottom of the drop-down menu.
If you are using the Facebook app online, go to the "Upcoming" tab on the left, and to the right of "Recommended Shows From Today" there is a little black calendar with the number 31 on it. If you click on that calendar, you can choose a date to start seeing dates from.
