Well, I dunno about "leeway" and "roughly the same time". That suggests that it's not regular, precise, and very easy to figure out. There is a simple and very precise definition to a day which never varies, not even by a second. Just get a UTC clock — or figure out exactly when midnight UTC is in your time zone — and you'll be fine.

Having said that, there is an advantage to failing this task. As long as you don't win the badge for editing for a whole year, you can repeat the whole track. So the person who goes 364 days and takes a day off will get more points than someone who actually gets 365 days. Once you win the year badge, though, you can't repeat the track.
