Frequently Asked Questions

Q: Does this work with Google Calendar or Yahoo Calendar?

A: Yes! Here are the instructions for Yahoo, and here are the instructions for Google. The URL you will subscribe to is:

Q: Why do events such as the Full Moon have both a date and time?

A: Because the time shows the exact moment when the the moon will appear most full. Depending on where you are in the world, you will want to plan your full moon adventure on the night that is closest to the full moon. For example, the September 26, 2007 full moon happened at 3:45 pm Eastern Time. If you were in Europe, that was 7:45 or 8:45 pm. If you were in New Zealand, that was 7:45 am on the following day – September 27th. So if you were in London, you’d want to howl at the moon on the night of the 26. But if you were in New Zealand, it’s the night of the 27th when the moon appeared brightest.

* Event times in this calendar are entered as UTC or Mountain Time – but your software should automatically convert to your local timezeone.

Q: How do I unsubscribe?

A: That depends on your device or software.

Just try googling for something like, “how to unsubscribe calendar iPhone”.

Another way to say thanks is to buy yourself a present! If you purchase anything from Amazon after following this link I get a 5% kickback from whatever you’ve added to your cart. (It doesn’t cost you anything extra.) How about:

A great starter telescope because it doesn’t invert the image. Dual purpose, you can also spy on your neighbors.

This affordable spotting scope comes with a mini tripod and an attachment for taking photos with your cell phone.

Canon 18×50 image stabilized binoculars will change how you see the moon and stars forever. Electro-optically stabilized so don’t even need a tripod. Huge glass that gathers tons of light.

“I absolutely am in love with your calendar and I’m so thankful for the work you put into it. I always missed events before but my daughter and I watched the Geminids together because of YOU! She is 10 and just loved it! So much so that she asked for (and received) a tent for Christmas so we could watch stars together and go in the tent to snuggle when we got too cold.”
