For the second year in a row, Aaron Watson has created a stunning 13 Moon Calendar. This 2021 Calendar is packed with the dates of observable astronomical events in the night sky - like meteor showers, eclipses, conjunctions, and more - that you won't want to miss.
Please note: The 2021 Calendars are normal wall calendar size (11"w x 8.5"ht.) - no extra large sizes this year.
The Calendar is based on the lunar synodic month - the amount of time it takes the Moon to orbit the Earth and return to the same phase. Month names are traditionally from the Iroquois Tribe. Also includes Astro Events and times (MST/MDT) each month so you can stay connected to what's going on in the night skies.
$20 each + $2.50 Shipping (Delivery and pick-up options available in and around Paonia, CO - please inquire for details).
Dedicated to the Dark Sky Movement - A portion of sales go to Dark Skies Paonia so we can continue our mission to preserve and protect our precious and wonderful night skies!
These calendars make great, unique gifts for friends or for yourself, and you will have access to dates with astronomical events occurring each month, along with these stunning images. Please consider supporting our efforts to preserve our night skies by purchasing a calendar for your home, office, family and friends!
