I'm very new to MongoDB and clear with the basics but got stuck at a point.
I'm working in MongoDB with a CSV file. In it, there's a column called 'Issue Date'. Some dates are represented as MM/DD/YYYY, the others as MM-DD-YYYY. I read in the documentations that MongoDB accepts the hyphen format(?). I don't know if I'm in the right direction, though.
Then, I have to divide them all into Seasons for NYC.
The CSV can be found here
