Remember this system would actually probably rely on the filianic year, So you would have to google the weekday of march 21st (or any other 1st of a filianic month) before your birthday. Which for you specifically would actually be Sai Raya
On the Chapel of Our Mother God website, it's been said that "the Janya ruling the year of one's birth is considered as significant as the ruling animal of one's birth-year in Chinese astrology" - how on earth can I determine which Janya rules my birth year? I'm still trying to understand the years and days in Deanism/Filianism and I don't know how to determine this for a year that was 3 decades ago.
Rayati! Thank you for sending me this ask, because while I knew about this vaguely I never actually bothered to think about it that much, and it really is interesting to me.
If I recall correctly, the Janya who rules over a certain year depends on the day of the week that year begins. For example, a year that began on Sunday, Rayadi, was ruled by Sai Raya. So a quick Google search of "What day of the week did [birth year] start?" should work.
For anyone who needs a refresher of the Filianic week, here you go:
Rayadi (Sunday,) ruled by Sai Raya
Candredi (Monday,) ruled by Sai Candrë
Vikhedi (Tuesday,) ruled by Sai Vikhë
Matidi (Wednesday,) ruled by Sai Mati
Thamedi (Thursday,) ruled by Sai Thamë
Sucridi (Friday,) ruled by Sai Sushuri
Rhavedi (Saturday,) ruled by Sai Rhavë
My birth year began on a Sucridi, making Sai Sushuri the ruler of my birth year. Neat!
