CREATE TABLE table_51435 ("Home team" TEXT, "Home team score" TEXT, "Away team" TEXT, "Away team score" TEXT, "Venue" TEXT, "Crowd" FLOAT, "Date" TEXT)

Can you tell me a date that has a crowd larger than 20,771, and a Venue at Windy Hill?
SELECT "Date" FROM table_51435 WHERE "Crowd" > '20,771' AND "Venue" = 'windy hill'
SELECT "Date" FROM "table_51435" WHERE "Crowd" > '20,771' AND "Venue" = 'windy hill'
