Clark's birthday takes place during "AKA Superman" which aired 3/16.
I personally always put his birthday in February. He was found 5/17/16 and he looked about 3 months old in "Tempus Fugitive". So I usually put it around 2/17. (Or perhaps Valentine's Day, but I don't know if Martha and Jonathan would be *that* cruel to Clark.) Clark doesn't know his correct birthday because he was born off-planet, so any date could possibly work.
RE: Lois's birthday. Yep, Libra (per "Contact"). I move her birthday around. In
Missing Lois it was at the end of Sept. to coincide with her jailtime. In
Green-Eyed Monster or more correctly
Nightfall Honeymoon I change it around so that their wedding date is towards the end of Sept. and make her birthday 10/6 (canon L&C's official wedding date).
