Hello, I previously asked a question about "Yesterday" but I didn't realize I was asking the wrong question. My script provides dates in a MMDDYYYY fashion. What I am seeking help for is to find the date of one day before the date that my script has provided. If it provided 04/24/2023 I need Perl to tell me the day before it or if the script provided 05/01/2023 (MMDDYYYY) I would need Perl to tell me that the day before was 04/30/2023 in this example. If Perl programming results in DDMMYYYY instead, I am OK with that; I can change it. I do NOT need DST or variables of it, I am not concerned with time zone because this computer will not be moving and the latter two items are not a concern. I only need Perl to determine the date before the date my script provides. I hope I explained myself better as I stumbled through this exercise of explaining what I need. Again, I thank all of you who have helped me in the last days and before that. Thank you again!
