Title: Do You Know These Interesting Facts about Calendars?


1
Fun Facts About Calendars
2
How did the word Calendar came into existence?
  • The word calendar comes from the Latin word,
    Kalendae, which means the first day of the
    month.

3
Who introduced Gregorian calendar to the world?
  • Gregorian Calendar, the most commonly used
    calendar today, was introduced by Pope Gregory
    XIII. This was because the previously used Julian
    Calendar was off by 11 minutes, causing the
    calendar to fall out of sync with the seasons.

4
How does the Gregorian calendar differ from the
Julian calendar
  • In the Julian calendar, every year divisible by 4
    is a leap year. However, in the Gregorian
    calendar, there is an exception century years
    are not leap years, unless divisible by 400. This
    was done to offset the miscalculated 11 minutes.

5
Why does the Gregorian calendar differ from the
Solar year by 26 seconds?
  • The exact time it takes for Earth to complete one
    revolution is 365 days, 5 hours, 10 minutes and
    48 seconds. By adding a leap day every 4th year,
    a difference of 26 seconds arises.

6
When was the new year celebrated before the
adoption of the Gregorian calendar?
  • Before adopting the Gregorian calendar, the
    English new year was observed on Lady Day, March
    25th, which celebrates the Virgin Mary.

7
When and Why did Sunday became the day of rest?
  • Roman Emperor Constantine chose Sunday as the day
    of rest and prayer in the year 321. He did so to
    please both Christians (Sunday marks resurrection
    of Christ) and Pagans (who worshiped the sun
    gods) in his empire.

How did the months of the year get their names?
  • January Named after Janus, the God of beginnings
    and endings
  • February Named after the festival Februa, a
    period of celebration
  • March Named after March, the Roman God of War
    (Originally March was the first month. January
    and February were added later by Numa Pompilius)
  • April There are three theories behind Aprils
    naming
  • It is the Latin word for second
  • Derived from Latin word, Aperire meaning, to
    open, representing the opening of buds in spring
  • Named after Roman Goddess, Aphrodite
  • May Named after Maia, earth goddess of growing
    plants
  • June Named after Juno, the queen of the gods and
    patroness of marriage and weddings
  • July Named after Julius Caesar in 44 B.C.

10
Is 13th more likely to fall on Friday than on any
other day of the week?
  • Yes, 13th of every month is more likely to fall
    on Friday than any other day of the week, 688
    times every 400 years to be precise. This is
    because after three 28-year rotation cycles, the
    last 12 calendars repeat themselves. Since 1st
    January of the 13th year falls on a Saturday, the
    distribution symmetry of days is disrupted.

11

world?

    calendar in the world. However, it isnt the only
    one in use. There are 6 other regular calendars

    based on earths revolution.
  • Calendars like the Islamic calendar are lunar
    calendars that are based on phases of the moon.
