daasyochid…I was refering to missing Yom Tov candlelighting bec. one fell asleep(not feeling well)and woke up the next morning realizing they forgot to light Yom Tov licht.
I don’t mean that it can’t happen. I mean since it’s unusual, there was no knas instituted.
This is actually, IIRC, a machlokes, in which l’maaseh we are meikil because it’a a safek k’nas.
