Yes but that extra day (day and a half is nearer)
would quickly make a difference, you'd be half a month
out after a year. There has been some talk of new year
on another list I'm on. January 1 was only adopted as
New Years Day in Britain in the middle of the 18th
century. before that Ladies Day (March 25) was
traditional, but there were plenty of variations. In
Australia bankers and accountants still celebrate New
Year on July 1, and in other parts of world other
dates are used. The muslim new year cycles through the
year as they use a Lunar calendar. Some calendars
combine lunar and solar elements (chinese), as does
the determination of Easter.
