I attempted to celebrate some of the Feast Days. The ones I understood. Im still studying them, but pray I observe them correctly.

Numbers 9
9 Then Yahweh said to Moses, “Tell the Israelites: 10 Suppose you or any of your descendants is unclean from touching a dead body or is away on a long trip. You may still celebrate the Passover. 11 You will celebrate it on the fourteenth day of the second month at dusk. You must eat the Passover animal along with unleavened bread and bitter herbs. 12 You must never leave any of the meat until morning or break any of the animal’s bones. You must follow all the rules for the Passover when you celebrate it. 13 But if you are clean[b] and not on a trip and yet don’t bother to celebrate the Passover, you must be excluded from the people. You didn’t bring your offering to Yahweh at the right time. You must suffer the consequences for your sin.
14 “Foreigners living with you may want to celebrate Yahweh’s Passover. They must follow these same rules and regulations. The same rules will apply to foreigners and native-born Israelites.”
