Every four years (more or less) we actually get an extra 24 hours, and that day is Leap Day, the paradox-producing Feb. 29 that helps balance out the extra minutes that accrue every year as the earth rotates around the sun in just over 365 days.
The extra day is an illusion, of course, a quirk of the calendar.
But still: If you had a completely free day -- away from work, away from responsibilities -- how would you spend it? Would you eat out? Use the time to catch up on chores? Or tour the city?
