Ahem. In low level, pointer oriented languages such as C and its
family. And those who chose to imitate it.

But not in the first language I used when working for a living (COBOL).

Nor FORTRAN DO statements. Most people start at 1. You can also
write an off-by-1 bug in loops depending on whether you start the loop
with 0 or 1.

And in C and most C-derived languages those off-by-1 bugs abound. I've
never done a formal count but I suspect that half the patches Microsoft
has issued for Windows fix off-by-1 bugs.

He's saying that people don't get time off work on account
of it. Which is doubtless true; I don't, either.

yes. it is not an official holiday, but there is a slowing down of
bussiness, as some businesses give employees vacation or have a
reduced
employee load. I am not a Christian, and while in college I had

There will be no garbage collection in the city'; ...".

"Le deuxième test classique donne en revanche des inquiétudes.
Historiquement, pourtant, l'explication de l'avance du périhélie de
Mercure, proposé par Einstein lui-même, donna ses lettres de noblesse
à la relativité générale. Il s'agissait de comprendra pourquoi le
périhélie de Mercure ( le point de son orbite le plus proche du
soleil ) se déplaçait de 574 s d'arc par siècle. Certes, sur ces 574
s, 531 s'expliquaient par les perturbations gravitationnels dues aux
autres planètes. Mais restait 43 s, le fameux effet "périhélique "
inexpliqué par les lois de Newton. Le calcul relativiste d'Einstein
donna 42,98 s ! L'accord et si parfait qu'il ne laisse la place à
aucune discussion. Or depuis 1966, le soleil est soupçonné ne pas être
rigoureusement sphérique mais légèrement aplati à l'équateur. Une très
légère dissymétries qui suffirait à faire avancer le périhélie de
quelques secondes d'arc. Du coup, la preuve se transformerait en
réfutation puisque les 42,88 s du calcul d'Einstein ne pourrait pas
expliquer le mouvement réel de Mercure."

suivante, Walter Adams mesurerait exactement ces 0.007%. Il s'avère
aujourd'hui que ces mesures , qui constituèrent pendant quarante ans
une "preuves" de la relativité, étaient largement "arrangée" tant
était grand le désir de vérifier la théorie d'Enstein. La véritable
valeur fut mesurée en 1965. Elle est de 0.03% car Sirius est plus
petite , et sont champ de gravitation est plus fort que ne le pensait
Eddington."

In the US, the is really no concept of "official holidays".
There is no law that requires any day to be a paid non-work
day for anyone. Instead, there are laws that require
employers to have a fair holiday policy that does not
discriminate against any religion. There are also specific
local laws that require certain business to be closed
on certain days (e.g., liquor stores on Sundays). Other
than these laws, basically every organization sets its own
holidays.

In any case, as a religious holiday Easter can't be a holiday
anywhere in the USA. Since it's always on Sunday, this has little
impact.

Thus, a "federal holiday" merely means that it is a holiday
for the federal government offices, post offices, etc.
Likewise, a "state holiday" means only that it is a holiday
for state government offices. Each school district (typically
one per town) sets its own holiday schedules, which may or
may not following the state holiday schedule.

Here in Tucson the local school district does not take the
President's Day holiday but gives the Thursday and Friday of
Rodeo Week off.

As an example,
the school district of town where I live has both Rosh
Hashanah and Yom Kippur as holidays even though the town
Jewish population is probably less than 5%. OTOH Good
Friday and Ascension Day are rarely holidays by themselves,
but the school board would try to schedule the 1-2 week
"Spring Recess" to include both of them. (For 2010, it
is a 10 day stretch that starts on Good Friday).

Constitutionally, public schools and offices in America cannot
have religious holidays. Many school districts will try to
schedule necessarily secular holidays to coincide with religious
holidays. For instance, there may be a "Spring Break Holiday"
which conveniently is timed to cover Passover, Good Friday and
Easter. This gets tricky when Easter falls particularly early or
late on the calendar.

I'm not clear on how a public school district can have Rosh
Hoshanah or Yom Kippur holidays. What town is that?

And, just in case someone was going to ask, Christmas has been
adjudicated to be a secular holiday.

A full-*ish* moon, actually. The definitions of the equinox and full
moon used when determining Easter are rather different from the real
definitions used by astronomers, which would actually give rise to
different (perhaps several weeks different) Easter dates depending on
one's longitude.

I suspect you don't know what or when Ascension Day is ...

Larger organizations in the US typically has some paid
"personal days" so that people can use take them for
religious or other reasons without explanation.

Btw, Good Friday is a Wall Street holiday by tradition.

I like the notes in _Programming Perl_:
