Displaying Data by Date

Hie there, im creating a shop management system for my parents i have created a" Products" Field which has (name, buying price, selling price, opening stock…etc) as entries in the Field" Products".i need help in displaying some data I am trying to create a workflow which when you select a date on a Date/Time Picker it Filters the entries which are in the Field "Product"s based on their Created Date,then displays the entries in a Repeating Group. The entries displayed should be the ones which were created on or entered on the same date as the date selected on the Date/Time Picker.
Thank you
