I was just made aware of a new Schengen Calculator app called Schengen Simple. It's available for Apple and Android. I gave it a try and it's easier to use than the others--at least in my opinion. It does cost $10/year but you get a week free trial.
I don't have any connection to this app but I thought I'd share it with others.
The Schengen website has a calculator for calculating days left. Not sure how easy it is to use. I guess the rule is 90 "calendar days" (not 24 hour periods) in a 180 "calendar days" period. Seems you should be able to do your own calculations on any spreadsheet program.
This also seems like a problem most normal people would not have. Although I have historically spent less than $100 a day on the ground in Germany (accommodations, meals, in-Germany transportation, Misc.), I really wouldn't want to spend that much (plus, the cost of not being at home, like boarding a dog, would be a considerable addition). Might be an issue for someone doing a lot of business in Europe, like Rick?
Another free Schengen calculator is at https://www.visa-calculator.com/. I find this one easier to use than the "official" one.
Lee, perhaps I'm not "normal," but last year I ran within about a week of overstaying in the Schengen zone. I was visiting Norway and wanted to extend my trip somewhere else, but when I used the calculator to determine how many days I had (based on my previous trips), I realized I had to extend it outside the Schengen zone. I went to London for a week. Which was great.
