SQL Basics Code Challenge 1 of 1.

I cannot get by this one, and it seems relatively simple, here's the question: We're back in the sports team database. There's a results table with the columns id, home_team, home_score, away_team, away_score and played_on . Find all the matches in the results table where "Hessle" was playing away as the away team and if they played on or after October 1st 2015. Date format is "YYYY-MM-DD". Type in your command below. And my code: SELECT * FROM results WHERE away_team = "Hessle" AND played_on >= "2015-10-1"; It returns an answer, but I'm told it doesn't include October 1st! but I HAVE the greater than or equal symbol in there, doesn't that include it? Or am I doing it wrong? Arggh!
