I'm not sure if anyone geeky enough to care about these sorts of details has found their way to tvmaze yet, but if so I'd love to hear some opinions about this.
The issue is episodes that air after midnight, such as Craig Ferguson or Seth Meyers. If an episode airs in the night of Monday October 20 to Tuesday October 21, should we note the airdate as october 20 or as october 21?
Of course technically once midnight has passed the date has changed, so the correct airdate would be october 21. Though some (most?) other sources out there consider such episodes as part of the previous day, and thus use an airdate of october 20, which is technically incorrect but might "feel" like the most logical thing to do. We aim to gather the most accurate data as possible, but I'm not sure about the right thing to do here.
Please note that either way this won't affect the schedule you will see on the site or in our API: these are smart enough to include all episodes until 04:00 AM the next day.
