I'm pretty sure I've visited Stack Overflow and Meta Stack Overflow every day before 4 PM PDT (midnight UTC) for the past 50 days. I can recall seeing it say (I believe) 35(?) consecutive days visited a few weeks back. Then, all of a sudden, the counter reset on both sites. That got me wondering:
Say you visit at 6:30 UTC, would not visiting until 6:35 UTC the next day reset the counter, or do you just need to visit once every UTC day?
