It’s hard work being a werewolf, and I don’t just mean cleaning blood stains out of the carpet or dealing with fleas in the house.

It’s this messy business of the full Moon. Most wall calendars and news sources, if they even mention Moon phases, there’s about a 50/50 chance that they’re off by a full day (explained on the “Moon Facts” page). You might be out at a fancy event wearing a rental tuxedo when things turn weird. There goes your deposit. So awkward.

The only way to get a correct Moon phase for your time and location is with math and science. Our Matrix Portal Moon phase clock lets you know where things stand right here and now, portraying the Moon’s phase more accurately than a printed calendar, and whether it’s currently in the sky or has set.

So now you can prepare. No tux! Stay home and put on a comfortable flannel shirt like werewolves do.
