Addition subtracting date

hello a person to help me please
in input (initial content)
I put {get end date from page url - get start date from page url:format as days }
(content format) { text numbers only} why I get 19539 instead of 0 since it is the same date

Most likely your start date is empty or not a valid date format… (so it will default to 1st Jan 1970 - hence 19000 days)

What does the actual URL look like?

ok I see but I don’t understand your question about the url what should I check and how

I succeeded thank you for guiding me well
