I have seen a lot of info on how to subtract one datetime from the other and how to add years on to a datetime. but the following is giving me a headache....
When a user inserts a record a hidden field called subdate with a value of datetime.now is added to the db.
I then need to have an 'old records' page that lists all the entries that are over 1 year old and was hoping to use something (but using subtract method) similar to;
(DateTime.Now.AddYears(1))
but there is no SubtractYears available? Why?
Please can you let me know how I achieve the same result?
DateTime.Now.AddYears(-1)
From the documentation :
A number of years. The value parameter can be negative or positive.
now = datetime.now()
last_year = (now.year - 1)
datestr = (datetime.strptime(str(now.year - 1), "%Y")).strftime("%y")
print(f"Last Year: {datestr}")
The output will be:
Last Year: 20
If you prefer to have four digit year then change %y to %Y
