Publisher's Synopsis
This is an agenda or diary with the dates in both calendars: the Gregorian Calendar currently in force throughout the world and the Perpetual Rational Calendar. During 438 years the time has been measured in almost all the world using the Gregorian calendar established by Pope Gregory XIII in 1582. Although this calendar corrected some errors or imprecisions of the previous calendar, it has conserved until today some characteristics that are considered inconvenient to govern human activities: - The months do not have a constant number of days, but vary with 28, 30 and 31 days. This feature makes the entire calendar not permanent and that forces the continuous printing and mass dissemination of calendars and almanacs for each year.- If the year is divided into four "equal" parts that would be the quarters, it turns out that the first quarter has 90 days, the second 91 days, the third and the quarter have 92 days. If the year is divided into two semesters, the first one has 181 days and the second 184 days.- Does not take into account the lunar cycle that has so much influence on nature on the planet, regulating the tides, plant and animal physiology, the cycle of fertility of women, human activities such as agriculture, medicine, navigation, among many other influences.For this reason, a new calendar for humanity has been proposed for more than eighty years and, taking advantage of the resources offered by the Internet, signatures are being collected to request the United Nations and other international organizations to establish a new global calendar. A new calendar that has received several names, but in essence all agree on the following characteristics: - The year is divided into 13 months, all of 28 days, which coincides with the thirteen lunar cycles that occur in a solar year.- Because 28 is an exact multiple of 7, each month will have 4 exact weeks and therefore all months are identical and easily memorized. Every month start on a Monday and end on a Sunday.- 13 months x 28 days results in 364 days and an additional day is added, the first day of each year, which will always be a Sunday and will be the "F Day" which is the Family World Day. Because the last day of each year (28th of the thirteenth month) is always Sunday, there will be two consecutive Sundays that will have in the middle the night of New Year.- In leap years, another Sunday is added at the end of the year to be the "P Day" or Peace World Day. Therefore, at the end of the leap years there will be three consecutive Sundays: the 28/XIII, the "P Day" added and the "F Day" of the following year.
