I run this code and keep getting 1.5 as dailyFine. Not 1.4 as shown in explanation and as should be for 14 days.

Indeed, if you check the 'daysLate' value, it gives '15'. Why? Snapshot:https://w.trhou.se/n0iw7i49xy

The snapshot you posted above works as expected for me. dailyFine is 0.1, daysLate is 14, and balance is 1.4. I would try a hard refresh, but I can't think of a reason why it might be coming back differently for you with the same code. If you're still having issues, what browser are you using?

I'm not seeing the issue, the "daysLate" amount logged on the console is 14.

But where's the code that you use to show the amount?

Strange. I still get 15 days and 1.5 as balance. I updated the code with 'console.log(patron.balance);' to see the balance as well. Here is the snapshot once again: https://w.trhou.se/5xt1d87pl0. Please let me know, if you know what can be the issue. I use Google Chrome Version 77.0.3865.90 (Official Build) (64-bit)

I'm still getting the expected behavior.

With the way JS implements Date, this shouldn't matter - but what timezone are you in? If you log out now and dateDiff, what do you get?

Hi rydavim ! I am in Helsinki timezone: Eastern European Summer Time Time zone in Helsinki (GMT+3) Friday, 18 October 2019, 10.29

I get these answers: dateDiff: Thu Jan 15 1970 02:00:00 GMT+0200 (Eastern European Standard Time) now: Fri Oct 18 2019 10:36:06 GMT+0300 (Eastern European Summer Time) Something wrong with dateDiff variable, isn't it? I wonder, why does it work in your region...

I have same issue and I don't see any solution so far. To get the same value of fine I have to manipulate the days from when It counts the fine.
