Religious calendars.

The calendar isn't only
used to know the day
of the month or the month
of the year.
The calendar is also
used by people of different
religions to appoint
religious events and to
appoint days, for example,
of celebrating rituals and
pilgrimages.
People were very conscientious
with carrying out ceremonies
in the past.
If mankind didn't conduct
these at the right time
or the right day,
the rituals could have
a bad effect and
make the gods mad.

The Hindoo-calendar.

The Hindoo-calendar is used
in the religious life of
India and with the Gregorian
every day.
Hindoos see the world as a
sequence of time cycles.
A cycle consist of 12000
divine years.
A divine year is 360 solar years,
so a cycle is 4320000 years.
Thousand cycles are a Kalpa
together. A Kalpa is
one day in the life of
the god Brahma, the creator
of the universe.

The Jewish-calendar.

The Jewish-calendar goes
back to 3761 before Chr. ,
which was for the Jews the
day of the creation.
This calendar is based on
the moon attitudes.
A Jewish day begins and ends
on sunrise. Every Saturday there
is the Sabbath, the saint day.
In the old Jewish-calendar
50 was a saint number.
Every 50 year guilds of people
were remitted and
slaves got freedom.

The year of the Islam.

The Muslim calendar begins
on 16 July 622 years after Chr.,
the day that the prophet
Mohammed ran away of his enemies
from Mecca to Medina.
This journey is known
as the Hijrah and the
calendar as the Hijri.
Every month begins with new
moon and the Muslim year is
11 days shorter than
the Gregorian year.
The year 1997 from the
Gregorian-calendar is similar
to the year 1417 from the Hijra.
The most important month
of the Muslim calendar is
the Ramadan, the month
of fasting.
During this month Muslims
mustn't eat, drink and
have sex between
sunrise and sunset.
During Easter, one of the
most important Christian
holidays, Christians commemorate
the crucifixion of Christ.
Earlier, the Christians had
problems with deciding on which
day Easter should be celebrated.
In 325 after Chr., it was
decided that Easter would
be on the first
Sunday after the first
full moon, after the vernal
equinox.
(about 20 March)
This means that the date of
Easter could vany by
more than one month,
namely from 22 March
till 25 April.
