the date() function returns the number of days since 01.01.1900 for the local date of the current system (related to the system clock of the OS).
If you travel from Germany to the US but don't update your date/time settings, then it returns the same date in the US as in Germany.
You can check the behavior by changing your local date/time setting or the timezones.
Thank you. Got it.
Do we have any chance to get it from IP address or interner provider date, format by using any JS?
