How a sleep count works
The convention: one sleep means one night still to go. On the morning before, the answer is one. On the morning of the day itself, it is zero — you have run out of nights to sleep through. Because it tracks nights rather than 24-hour periods, the figure can read one higher than the day count for an event that lands in the morning.
