I am trying to generate synthetic data of previous days from a dataset . How can I include the needed date in the program?

Question

i have generated the new data using ctgan but it creates in same day as in dataset (13-09-2022 and 14-09-2022). I want the dates previous days(like 12-09-2022,11-09-2022...) ,can anyone help thank you in advance

from ctgan import CTGAN
ctgan = CTGAN(verbose=True)

ctgan.fit(data, categorical_features, epochs = 100)
samples = ctgan.sample(10)

output-     visit_date  token_no    patient_booking_time    
0   2022-09-14  260 11:01   
1   2022-09-13  237 10:00
