    Default Vietnamese Date - B.P.

    The brochure of the Cần Thơ Museum gave the date of an object as "1675±45 B.P. tức là 275±45 năm sau Công Nguyên."

    What is "B.P."? What is its origin?

    Thank you.

    Sau công nguyên là AD, trước công nguyên là BC.
    thí dụ: in 89 AD = vào năm 89 công nguyên (chữ sau là thừa, không nên nói năm 89 sau công nguyên)
    in 567BC = vào năm 567 trước công nguyên ( trường hợp này có chữ trước)

    còn BP thì chỉ thấy ở dầu nhớt British Petroleum

    http://en.wikipedia.org/wiki/Before_Present

    Before Present (BP) years is a time scale used in archaeology, geology, and other scientific disciplines to specify when events in the past occurred. Because the "present" time changes, standard practice is to use 1 January 1950 as the arbitrary origin of the age scale. For example, 1500 BP means 1500 years before 1950, that is, in the year 450.
