Check out the "What is a Day?" interactive video at
It's super cool!! (and made by Jasper Palfree & the MinuteEarth/MinutePhysics team)

The MinutePhysics video about Why December Has the Longest Days:

This video is about the length of a solar day vs a stellar day vs a mean standard day, what they all have to do with each other and the earth's orbit, eccentricity, axial tilt, and so on. Also, aliens and asteroids. It'll explain the equation of time, and why the longest day is in December. The lab will also show you what days are like on all the other planets - Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and even - though it's not a planet - Pluto.
