Countdown to Equinoctial Planetconjunction (CEP)
personal earthday count (pec).

A new timekeeping concept from CALENdeRsign


Before presenting the innovative timekeeping systems CEP and pec we want to introduce you some principals of time. This is necessary to understand this concept being in harmony with ancient and modern timekeeping. One dimension of timekeeping is the calendar, which counts now the years since the epoch of A.D. fixed by Dionysius Exiguus in 6th century.



 It is interesting that epoch (from Greek epoch = stop for a short period of time) and moment (from Latin momentum = reason of movement, point of time, juncture): the certain point of a movement, as it stops for a split second and thus loses velocity. Simply and in brief, movement without velocity is a moment, like one single frame from a motion picture film. 

Time and space are linked with each other by velocity.
The formula is: Time = distance/velocity. Velocity therefore is distance/time, expressed in m/sec, km/h or lightpath throughout one year, i.e. the distance the light goes in one year. 
We see that to measure the time exactly we need something that moves with invariable speed and an exactly defined spatial distance between starting point and finish.

Actually we have another fundamental type of time measurement system that uses cyclical periods. Its fundamental quantity, the second, once was determined by Earth’s rotation, or briefly the smallest naturally given component of the calendar which is the the DAY. Its length does not depend on the watch, but only on the position of the sun!

To measure time we have clocks that use more precise natural constants or periods than the uneven movements of Earth like rotation (day) and orbit (year). The definition of one second is no longer 1 / 86,400 of a 24-hour day, but a certain multiple of the period of oscillation of a Cesium atom. According to international agreement (SI) one second is 9192631770 times the period of the radiation that corresponds to a flapping of the 133Cs outermost electron's spin from -1/2 to +1/2 (or backwards).

Because Earth rotation and orbit are not invariable,  are added about once a year into  (UTC) time scala. The Earth is constantly undergoing a deceleration caused by the braking action of the tides. Through the use of ancient observations of eclipses, it is possible to determine the average deceleration of the Earth to be roughly 1.4 milliseconds per day per century. This deceleration  causes the Earth's rotational time to slow with respect to the atomic clock time. The length of the mean solar day has increased by roughly 2 milliseconds up to year 2000 since it was exactly 86,400 seconds in about 1820. Therefore leap secondsmust be interpolated once or twice a year into  Universal Time Coordinated ( UTC) because of the irregularity of Earth’s rotation, to keep UTC on the right “start-of-the-day” track, like a ship in a stormy sea in its course. If these leap seconds were not added, the UTC midnight-clock would eventually ring at sunrise after many years. The “hourly time ship” would drift off its course. See the diffrence of UTC and TAI seconds. TAI is the International Atomic Time scale, a statistical timescale counting continously "atomic seconds only" based on a large number of atomic clocks.

Leap days keep the “calendar time ship” on its course and the seasons in their definite places in the solar calendar and the moon phases in the lunar calendar. Leap days that do not conform with Earth's movements would make the “calendar ship” drift off its course. This was for example the case with Julian calendar and cause of the Gregorian reform. The leap day rule of the Gregorian calendar already requires another correction,  because the vernal equinox soon will take place on March 19th.

Let us now take a short look at the history and  the character of calendrical timekeeping:
The whole day, which is composed of daylight and night due to sun's position, is the fundamental and undividable base of the calendar. Therefore we measure it by the angle that the sun describes, as observed during one Earth’s rotation. Please note that this angle is not 360°, but a bit more, because in one day, Earth has moved forward on its orbit in respect to the sun and therefore has to rotate forward the angle a, to return to the same position as at begin of the day. 


(The red point marks a position on Earth's equator) 
In one day rotation of Earth is 360° + a


Please note: The essential moment or starting point used to measure calendrical time is a celestial alignment. The actual event of an alignment means that three different positions in space are located along a line, just as if you aim with a rifle. The three points in a line are given with the eye, the aiming device and the target. Any planetary alignment is formed by Earth and two planets in a straight line, and the period of such alignments is given by the amount of time, as long as it takes from one such alignment  until the next. Usually we forget that the observer or the point of observation always represents one of the three positions. In the case of the above mentioned measurement of the day lengths at start at lower culmination (midnight) the three points are: (red) point of observation on equator; center of Earth; center of the sun.

Because of Earth's movement we have several quantities for calendrical periods:

  • The day:
    It is the amount of time between one sunrise (alignment of the sun with the horizon) until the next, or more precise, the duration between two lower culminations of the average sun. Don’t forget that the position of the observer is always important too.
  • The lunar month:
    It is the duration from one alignment of Moon with Sun until the next, or one New Moon to the next as observed from Earth.
  • The solar year:
    It lasts from one alignment of the sun with the point of equinoxes or solstices to the next as observed from earth and is called the tropical year. We may define the calendar year which is determined by the number of its days and an arbitrary leap day rule such as e.g. the Julian or the Gregorian.
  • Planetary periods:
    In many ancient calendars we find planetary periods, such as the first visibility of Venus. Simply explained, this is the moment of the heliacal (first morning) rising of a planet after its alignment with the Sun several days earlier. The duration between two such moments results in the synodic period of the planet.
  • The Ages:
    To determine the ages or eras also the precessional shift of the equinoxes due to wobble of Earth’s axis is taken into account for timekeeping, which gives the Platonic month, resulting in the Platonic year. Since ancient times the heliacal rising of a new spring equinox constellation is very important.

Now shall be shown the fundamental difference between physical time of a watch and calendrical time, based on Earth’s movement:
Calendrical time spans, expressed in calendar days or calendar years, at first glance represent peculiarities in quantities of measurement. Their components are not such familiar time spans as hours, minutes or seconds, that are referenced to atomic oscillation.

As paradoxical as it sounds, it is very simple: Self-referential is the right expression to explain the characteristic of a calendar: days and year refer to each other. The number of days determines the duration of the year and vice versa, the duration of the year determines the number of days.

A correct calendar references only the movements of Earth and puts the days and the year in relation.
How does this work?
Astronomers measure with highest precision the duration of  Earth’s rotation and Earth’s orbit and express it exactly in split seconds, using atomic oscillation.

To create a solar calendar it is important, how many average synodic Earth’s rotations (days) fit into Earth’s orbit (tropical year), because this gives the numbers of the days in a year and is the base of the leap day rule.

Let us call the number of seconds (or oscillations) of an average earth rotation “d” and the number for the orbit “y”. This results in the very simple formula:
x * d sec = y sec; how many "d sec" (seconds of a day) result in the "y sec" (seconds of a year); 
x = y/d
The result is the fraction of the y/d and gives the average amount of days in a year or vice versa, what part of a year is the day. The quantity "second" is reduced at this fraction.

d sec : Average synodic Earth’s rotation from lower sun’s culmination to the next, expressed in seconds of cesium atom periods
y sec : Average Earth’s orbit between two equinoxes (tropical year), expressed in seconds of cesium atom periods
Both values are measured with watches using the cesium atom period. 

Calculated with currently most precise data the reckoning is:

d = 86400.002 SI sec;  or 794243403313263,54 of 133Cs periods
y = 31556925,974592 SI sec; or 290091200277572631,98784 of 133Cs periods

x (number of average days in tropical year)  = 365,242190325319668

The calendrical time is independent of the physical time of a watch. It may sound like a paradox, but the calendrical time is not affected, if Earth’s orbit and the rotation of Earth slows down in same ratio. The number of days in a year would be the same, though our watches would show more than 24 hours a day. Physically considered quantities like calendar days or calendar years are numbers without physical dimension. The final reason, why the calendar does not have any physical dimension is that it is composed of angles between different alignments put in relation to each other. Or, compared to a watch: The hours don’t go faster if the watch is huge or slower if it is tiny.


The Julian Day Count


Julian day refers to a continuous count of days since the beginning of the Julian Period used primarily by astronomers.
The Julian day number is based on the Julian Period proposed by Joseph Scaliger in 1583, at the time of the Gregorian calendar reform, as it is the multiple of three calendar cycles used with the Julian calendar:
15 (indiction cycle) × 19 (Metonic cycle) × 28 (Solar cycle) = 7980 years

Scaliger assigned in a cabalistic, arbitray or superstitious way to the year 1 A.D. the numbers 3 (Indiction) 1 (Metonic) and 9 (Solar). This has the deffect that he arrived in year 4713 BC., when this three cycles were assigned with the numbers 1(I), 1(M) ,1(S). — Scaliger chose this because it preceded all historical dates.

Because this day count is based upon religious and superstitious arrangement it is esteemed as beeing corrupt and outdated by secular astronomers.



As can be shown in many cultures and calendars a close massing of all classical planets was decisive for eastablishing of new eras or ages.
Therefore as a commemoration, CALENdeRsign designed CEP (Countdown to Equinoctial Planetary alignment)
Is is a daycount towards the next close massing of all classical planets (togehther with Unraus and Neptun) at the most significant day of vernal equinox (20th March, 2675 CE).
The repetition of such an alignment on the calendrically significant spring equinox day occurs in average only after about 60,000 years, more than two precessional Great Years. Requiring that Uranus and Neptune be close as well, however, moves the probability that humankind will experience such an event again into the very far future.


For example:

Point zero of CEP is anchored at the alignment.

20-03-2675 =  CEP 0


Today's CEP date is: 

239496 Countdowndays until Equinoctial Planet-alignment: 20-March-2675 CE (CEP=0)




The current CEP date may be may be found always on the website of CALENdeRsign.


This way of  counting days provides us with an interreligious and global astronomy- and astrology-based, calendar system that is easily compatible with a new solar, lunisolar or planetary timekeeping system in future.

CEP could replace the Julian day count (JDN), which is based on superstitious medieval Christian mysticism. 

The conversion between  CEP and Julian Day Number, JDN, is easy:
CEP = JDN -2,698,162.
For example: 14 Feb 2003 CE, 12:00:00 UT has Julian Day Number  (JDN) 2,452,685.00000
CEP = 2,452,685.00000  -2,698,162  = -245,477

CEP provides us with a new anchorage in time that is not burdened by imprecise religious tradition, belief, or nonbelief.

The Grand-Year-Alignment of the spring equinox day, CEP 0 (March 20th, 2675), is mirrored on a scale of 1:1 billion in a 7 km-long park, called Planet Trail "HEAVEN on EARTH", located in a tourist area of the Eastern Alps of Austria.




As shown, CEP focuses on a specific day of future common orientation of time keeping with a daily count.

However, there also is available a past-oriented, individually and personally significant day count for everyone, and it begins on a date of which everyone is aware.

CALENdeRsign calls this count “pec” (personal earthday count). It counts the earthly days of anybody since the day of his or her birth.

You can retrieve your recent pec-date by simply sending an email with your birthdate to

This pec count provides you with a lot of new dates you can celebrate, such as any 1000th or 100th day living on Earth.

Did you ever think about celebrating your 10,000th day on earth at age 27  or your 20,000th day at age 54?

And what a surprise you could give your friends, congratulating them on reaching their 12,345th day at age 33, or the 22,222nd  day  at age 60, or any other day number that has personal significance, e.g:   7*7*7*7*7 = 16,807 days at age 46.

CALENdeRsign can provide you with any exact personal date or date difference you wish and a lot of surprising discoveries that results from this new count.

You can figure out for yourself the lucky number of days and devise your own methods of timekeeping, such as some companies that use shift work and thus don’t follow the Gregorian seven-day week rhythm.

We hope we have given you  new insights and ideas, not only about  the past, but also future timekeeping.

In closing we cite Friedrich Nietzsche, who wrote:
" …  time is reckoned since this dies nefastus (day of bad luck), with which the disaster started, - since the first day of Christianity! – Why not reckon from his last day? Since today? – Let us reconsider all paradigms!"
