The Data Clock

• There are 24 hours in one day
  • There are 1,440 minutes in one day
  • There are 86,400 seconds in one day
  • There are 86.4 million milliseconds in one day
• The Lunar or Zodiac Calendar follows the full moon with each sign starting on the full moon. This is confusing because some interpret this calendar from the perspective of these signs starting on a new moon rather than a full moon. 
  • Aquarius Jan 20 - Feb 18; Pisces Feb 19 - Mar 20;  Aries Mar 21 - Apr 19; Taurus Apr 20 - May 20; Gemini May 21 - Jun 20; Cancer Jun 21 - Jul 22; Leo Jul 23 - Aug 22; Virgo Aug 23 - Sep 22; Libra Sep 23 - Oct 22; Scorpio Oct 23 - Nov 21; Sagittarius Nov 22 - Dec 21 and Capricorn Dec 22 - Jan 19
• The Millennium Bug of 2000 was caused from some computer programs written before 2000 not working after 2000. Most of these problems were resolved before that day and this problem was avoided but it is should not be considered a ruse it wasn't one! Most of the programs written in COBOL had this problem and had to be replaced. COBOL was later scrapped by IBM because they couldn't fix the problem with it.
  • Another Millennium Bug is Jan 1, 2040 70 years after the UNIX clock started in 1970. Created in 1969 UNIX had the same problem most programs had in 2000 where they wouldn't work beyond that date. The problem with the UNIX clock can be avoided and probably will now that we are using 64 bit machines. The problem with the UNIX clock is it counts upwards from this date in the past and the number may grow too big to be stored after this date so it would crash with a buffer overflow condition.
• AD (Anno Domini) or ACE (After Christ's End) in the Georgian Calendar is the year Jesus Christ was crucified and the calendar counts up from this date. The Romans were not accurate so this is probably not accurate either! Experts believe it could be wrong by up to 12 years with the real date of the crucifixion.  
  • BC (Before Christ) in the Georgian Calendar is the year Jesus Christ was born and it counts backwards from this date. The Romans were not accurate so this is probably not accurate either and some believe it may be wrong by up to 30 years because Jesus' parents hid him from the Roman Emperor of the time who wanted him dead.
    • The problem with the Georgian Calendar is the earth spins at different speeds during the year slowing down in the winter months and speeding up in the summer months but the calendar does not compensate for this so every leap year has 29 days instead of 28 at the end of February to make it more accurate with the earth's rotation. This unfortunately is not enough with days having to be removed and added to the calendar periodically to keep it  accurate. 
• There are 12 months in a year
  • There are 365 days in a year
  • There are 52 weeks in a year
  • There are 7 days in one week
• A decade is 10 years
• A century is 100 years
• A millennium is 1000 years
