CREATE TABLE table_name_16 (date VARCHAR, week VARCHAR, opponent VARCHAR)

Can you tell me the Date that has the Week smaller than 13, and the Opponent of green bay packers?
SELECT date FROM table_name_16 WHERE week < 13 AND opponent = "green bay packers"
SELECT "date" FROM "table_name_16" WHERE "green bay packers" = "opponent" AND "week" < 13
