This is a once in a lifetime moment where the two coincide!
So it will happen again in Season 82 (January 1st 2029). However, as there seems to be a bisextile year sometimes between Season 82 and Season 123, it will be pushed back to January 2nd 2040 and so on afterwards.
Like I said, once in a lifetime. I'd be surprised if humanity can keep ourselves alive until then, let alone have BB still going. Here's to hoping 2018 is less apocalyptic than 2017, and BB has a resurgence.
