Get previous dates in sequence

Question

I have date that I get from Date Time Picker for example
string date1 = dateTimePicker1.Value.ToString("yyyy-MM-dd");
It gives me 2017-12-23
Now I need previous date to save in date2 variable
string date2 = "code for this"; // it should be 2017-12-22
Please help.
