Refactor past and future to use date fields (devopsdays#885)

* Refactor past and future to use date fields

Do not merge this yet - the /events page is displaying oddly,and it’s somehow due to the two New Yorks. If you change the startdate of New York (Winter) to be in 2012, everything lays out properly.

* Make tiny comment change to trigger deploy preview

* Change to three columns from four

For some dumb reason, this works, and it’s Probably Fine.
