Mongoose get list of users who bought a ticket everyday of the week

I'm creating a product for a company, and one of the feature is that they want to award any user who buys an item everyday for the 7 days of the week.
I'm currently using node, express, and mongoose.
So how do I get the records of only the users who bought at least an item everyday for the seven days of the week. This draw will be made every weekend
