PRESS RELEASE. METEORITE PISTOL HOAX? Feb 29 2016 I would like to correct the record.  We have previously stated the Gibeon meteorite from which we have constructed the Big Bang Pistols are being constructed is 4000000000 (FOUR-BILLION) years old.  I'm not sure if this estimate allows for the leap year (FEB 29). The Earth takes around 365  days (actually 365.24219 days) to circle the Sun (that's a solar year) which means our calendar is out by about a quarter of a day a year.  Therefore…

A very important calendar that the Maya used was called the Haab’. The Haab’ is a secular calendar that has no religious or spiritual basis associated with it.  This calendar simply counts a solar year of 365 days. Unfortunately, this calendar does not account for the extra quarter-day each year it takes the Earth to revolve around the sun. Our modern calendar corrects for this calculation offset by adding an extra day to February every four years, making a ‘Leap Year.’ The Maya didn’t…

Julian calendar - Wikipedia -a leap day added to Feb every 4 years, on average 365.25 days long. Approximates the tropical (solar) year. Greek astronomer Hipparchus; tropical year was a few min. shorter than 365.25 days; year gained about 3 days every 4 centuries Corrected by the Gregorian reform of 1582 by Pope Gregory XIII, years evenly divisible by 400 remain leap years. In 1582 Oct 5 became Oct 15

The Jalali calendar was introduced by Omar Khayyám alongside other Mathematicians and Astronomers in Nishapur, today it is one of the oldest calendars in the world as well as the most accurate solar calendar in use today. Since the calendar uses astronomical calculation for determining the vernal equinox, it has no intrinsic error, but this makes it an observation based calendar.
