Dear Editor,
The Gregorian calendar, with 97 leap days per 400 years, is a clumsy
approximation to the tropical year -. 365.2425 days as opposed to
365.2422 days, (Geoff Dobson, The Phoenix Astronomical Soc., May 2oo8
newsletter.)
The Gregorian Calendar's distingui****ng merit is that the days of the
week, Sunday to Saturday, repeat after 146,097 days cycle. (Maths
14-63-07 minus 210.)
365*400 +100 -4 +1. days. XXXX
Another speaker, Luca Quaglia 'The Sun in the Church' (WASS 2oo8),
argues for Equinoctial year and Dynamical time. (Alan Gilmore, Mt
John Observatory, Radio NZ, 22-5-08.)
Apparently, Archimedes and Euclid possess the mathematics required for
leap year and Antarctic circle - Don McDonald, A =3DPI* X^2, Area of
Compass circle on a Sphere. (Cover, NZ mathematics magazine 25 (2).
Aug 1988.)
What is the Minimum Distance that a polar satellite can 'snap' the
Arctic Circle, etc.?
Google: Donald Stuart McDonald, World Mathematical Year 2000.
Ideas_poster_13 to 22. (?)
How many full moons cover the celestial sphere to make daylight?
Tip . (sin .25 =BA )^ -2 =3D 52 525.25. It's a nice equation=97BUT
WRONG.=
Don hobby page 'gadot', Paul Moss.
'Easter Greetings', Dominion Post Wellington 29/3/2008.
Therefore, Polar Cap =3D (sin (23.5 =BA/2))^-2 =3D one 24.11th part of
sphere. (??)
FROM N Earth radii above surface, a weather satellite glimpses
instantaneously N / (N+1) of hemisphere EXACTLY!
Casio Fx-82 school's sci-calculator says;
Continued Fraction Convergents =3D [365; 4,8,-4,5,-3/10.]
=3D 365 +1/( 4+1/ (8-1/(4+1/ =85=85=85=85=85=85.* EUCLIDEAN algorithm.
Everyone should see that 8 leap years every 33 years =3D 365.242424
days is closer to 365.2422 than the Gregorian calendar, 97/400 =3D
365.2425 days.!!!
The 4th 8 12 16 20 24 28 and 32nd years of 33 year cycle would be leap
years.
How do we calculate 100*cc + yy. EQUALS (cc+yy) MOD 33. because 100
=3D 3*33+1.
Add Hundreds and cents.
However, in my opinion 31 leap years every 128 years is the ultimate
leap year calendar for CE. Common Era. =3D 365.2421875 days. Every
4th year except multiples x 128 =3D=3D 2^7th.
Year 2048 =3D 2^11th will be an unusual 'common year.'
Oooooooooooooo --- ooooooooooooooooo.

I have been sceptical x 8 years.
Have the astronomers observed the regular periods of
2x gas giant planets?
5ooo light years.
Can you prove it?
Query mistake.
e.g. could be occulted by a nearer asteroid or planet. ??? xx
Or meteorology.
Article assumes, does not give information.
Micro-gravitational lensing??
Is there an easier explanation.
Is the experiment repeatable.?
365.242424 days =3D
8 leap years every 33 years.
=3D 24 leap years / 99 years.
=3D .24 24 24=85=85=85. / .99 99 99=85=85=85..
1980=3D 19+80 =3D 99 leap year.
=3D 0 mod 33.
Every 4th years.
1980 + 4 8 12 16 20 24 28 year
=3D 1984--- 1988=85.2000 2004 2008. today. This year
Next leap year in FIVE 5 years.
2008+5 =3D 2013 (NOT 2012., delay 1 year.)
20+13 =3D 33
=3D 0 mod 33. (remainder on division. e.g. 12 hrs
o'clock -> 1 o'clock.)
400 year Gregorian calendar.
365.2425, less accurate// equinoxial year.

Excellent talk , Thursday 14/2/08.
=3D 365*400 + 100 =96 4 +1
=3D 146097 days A WHOLE NUMBER OF WEEKS IM****TANT.
The calendar days of week repeat.
=3D 14+7 +609
=3D609+21 =3D 630 =3D 7*90.

Secular drift. Tidal friction.
Therefore whole number of weeks.
