Religious Calendar

April-May 2017

The calendar below, created by Dr. Peter Yuichi Clark, is an excellent way to keep on top of religious high holy days and festivals as they go by. It is especially useful for those in interfaith vocations who need this information on a day-to-day basis.

TIO is cooperating with another “working” religious calendar project being led by Read the Spirit. It extends what we usually mean by religious calendar to include important civic holidays. It identifies major religious holidays more than a year in advance. Most important, it features stories about what these many religious festival events are all about – what they mean, the important stories, the food associated, and how particular events are celebrated. Your own stories of religious holidays, whatever your tradition, are welcomed at the site. Check it out!

April marks the season of Mmaal, which is when the rivers open, and of the Eagle Dances, when people of the Arizona Pueblo tribes dance to dramatize their communities’ relationship with the Sky-World. May and June mark the season of the Hopi Kachina Dances, in which Arizona Hopi celebrants represent various spirit-powers and perform ritual dances in open pueblo areas.  It is also the time of Yansa’altt, the season of berry blossoms—anticipating the berry harvest in summer, which is essential for survival in winter.
