Ethiopian Jews recently celebrated their festival of Sigd, which involves reacceptance of the Torah, communal fasting and feasting, and prayers.
Is it acceptable for someone of a Minhag other than that of the Beta Israel/Ethiopian Jews to celebrate Sigd? I ask because it is a holiday that doesn't exist outside of all non-Ethiopian traditions, but also doesn't conflict with Jewish beliefs. I've been in Israel during Sigd (though I wasn't this year), and wondered about "joining in" with my Ethiopian friends when they celebrated.
Obviously CYLOR, etc.
