1. JanuaryJanuary is the first month of the year in the Julian and Gregorian calendars, one
of seven Gregorian months with the length of 31 days. January begins
(astrologically) with the sun in the sign of Capricorn and ends in the sign of
Aquarius. Astronomically speaking, the sun begins in the constellation of
Sagittarius and ends in the constellation of Capricornus. January is named for
Janus,the god of the doorway; the name has its beginnings in Roman mythology,
where the Latin word for door comes from - January is the door to the year.
Traditionally, the original Roman calendar consisted of 10 months, totaling 304
days, winter being considered a month less period. Around 713 BC, the semi-
mythical successor of Romulus, King Numa Pompilius, is supposed to have added
the months of January and February, allowing the calendar to equal a standard
lunar year. (355 days)
January 1 - New Year's Day
January (third Monday) - Martin Luther King, Jr. Day
January 26 – India’s republic day

2. February
February is the second month of the year in the Julian and Gregorian calendars.
It is the shortest month and the only month with fewer than 30 days. The
month has 29 days in leap years. In common years the month has 28 days. Some
believe that February originally had 29 days but that idea was invented by
Sacrobosco during the Middle Ages. February starts on the same day of the week
as both March and November in common years. Having only 28 days in common
years, it is the only month of the calendar that once every six years and twice
every 11 years, will have only four full 7-day weeks where the first day of the
month starts on a Sunday and the last day ends on a Saturday. This pattern can
be observed in 2009 and can be traced back 11 years to 1998, another 11 years
back to 1987, and 6 years back to 1981.

months with a length of 31 days. March begins with the sun in the sign of

the Southern Hemisphere is the seasonal equivalent of September in the
Northern Hemisphere. The name of March comes from ancient Rome, when
March was the first month of the year and called Martius after Mars, the
Roman god of war. In Rome, where the climate is Mediterranean, March is the
first month of spring, a logical point for the beginning of the year as well as the
start of the military campaign season. Great Britain and her colonies continued
to use March 25 until 1752, the same year they finally adopted the Gregorian
calendar. Many other cultures and religions still celebrate the beginning of the
New Year in March.

effective in 45 BC. Astronomically speaking, the sun begins in the constellation of
Pisces and ends in the constellation of Aries. The "days of April" is a name appropriated
in French history to a series of insurrections at Lyons, Paris and elsewhere, against the
