Hi,
The Hebew calendar has it's own way of dating. Acoording to it we live in the year 5768, today is the 8th month, and it's the 9th day today in that month.
In the past they used to date as per the day the city of Rome was estsblished or to a year of a certain Caeser rulling (So the date was: Today is the 3rd year to Julius Caeser).
I am not familiar but the Chineeze people have a dating system of their own.
Best regards,
