Bug description

On March 13th and November 6th, and extra hour or 1 less hour is shown. I'd expect it to just look like a normal day with 24 hours (like google)

Expected Behavior

Only 24 hours are shown in a day, no more, no less

Actual Behavior

In the fall, one extra hour is shown. In the spring, one less hour is shown.
