Feast of Hordad

Hordad, Feast of

May, September, October; sixth day of Hordad, the third Zoroastrian month
This is considered a "sacred name day" in the Zoroastrian calendar because the same yazata or spiritual being, Hordad, rules the day of the week as well as the month. Hordad is a lesser deity who stands for wholeness or perfection; also known as Khordad, this spiritual being shares her name with the third month and the sixth day of the week.
The Zoroastrian calendar has 12 months of 30 days each, plus five extra days at the end of the year. Because of discrepancies in the calendars used by widely separated Zoroastrian communities around the world, there are now three different calendars in use, and the Feast of Hordad can fall either in May, September, or October, according to the Gregorian calendar.
There are about 100,000 followers of Zoroastrianism today, and most of them live in northwestern India or Iran. Smaller communities exist in Pakistan, Sri Lanka, Canada, the U.S., England, and Australia.
