    “Year 1601 (MDCI) was a common year starting on Monday of the Gregorian
    calendar and a common year starting on Thursday of the 10-day slower
    Julian calendar.

    January 1 of this year (1601-01-01) is used as the base of file date
    and of Active Directory Logon dates by Microsoft Windows.

    It is also the date from which ANSI dates are counted and were adopted
    by the American National Standards Institute for use with COBOL and
    other computer languages” [1]
