lua table range of dates

[benanderson_475]

How can i create a lua table of the last dates and days for the previous 14 day period, starting at today?  
I want to end up with {day 1 = {date = "8/19/2020", day = "wednesday"}, day_two = {date = "7/19/2020", day = "Tuesday"}....... }

i started with 

Code:

t = os.date("*t")
data ={}
today = os.date('%w') --%w weekday (3) [0-6 = Sunday-Saturday]
Index  = 1

for i = 1, 14 do

data[i] = today -Index
Index = Index+1

end

how can i filter out the -ve values and make it circular 0-6  to line up with the %w pattern
