The Intercalary Days

UCC Year
'Intercalary' Days are not part of the standard calendar cycle of the 12 'Triad' Months
They are inserted to keep the calendar perennial, the year 'in synch' with the equinoxes and to 'balance' the 4 Quarter Seasons, which would otherwise have different lengths

The standard (non leap) UCC Year is 'balanced' by 5 Intercalary Days

These are shown in the above graphic as Day 1 in the centre and Days 2, 93, 184 & 275 around the edge

Leap Years are balance by 6 Intercalary Days with an extra Day 0 inserted at the start of the year


The Intercalary Days are highlighted in the graphic below

UCC Intercalary Days

    This is based on the orbit of the Earth ⊕ around the Sun ☉ with its 2 equinoxes & 2 solstices as shown below

The Four Seasons

Note: This graphic shows the cycle rotated 90° anti clockwise from the previous graphic so you can see the angle at the 2 solstices better


The equinoxes & solstices create the 4 Seasons and together with the Sun ☉ at the centre give us the 5 Special Days each year (4+1=5)  

We can see this symbolised in the Ancient Solar (Celtic) Cross

Solar Celtic Cross

 And, the symbol for the Earth is '⊕' : a circle with a '+' added, based on this ancient symbol


Also, having developed the UCC based on this principle, I later came across this ancient archaic Mexican Calendar on Wikipedia!

Intercalary Day 1 - 'New Year's Day'

Inserted for the Sun ☉ and the start of a new yearly cycle

It is always the 1st Full Day After the occurrence of the Northern Hemisphere Spring Equinox, when the Sun crosses the celestial equator rising north and which I therefore call the 'Nobenox' (a contraction of 'North Bound Equinox')

(The 'Nobenox' itself is celebrated by Intercalary Day 2)


Intercalary Days 2, 3, 4 & 5  - 'New Season's Days'

These are inserted for the 2 Equinoxes and the 2 Solstices and their respective Quarter Seasons

Aries♈ Equinox

The 'Nobenox'

Cancer♋ Solstice

The 'Nolstice'

Libra♎ Equinox

The 'Sobenox'

Capricorn♑ Solstice

The 'Solstice'


Intercalary Day 0 - Leap Year's Day

Balances Leap Years
It is inserted before New Year's Day in Leap Years to make 6 Intercalary Days and 366 Days in total


All the Intercalary Days are also days within one of 4 'Cardinal Festivals'


Numerology of the Intercalary Days

There is a nice 'synchronicity' to the numerology of the intercalary days whereby:

their day of the year numbers reduce to their intercalary day numbers:

Day 000 of the year = intercalary day 0

Day 001 of the year = intercalary day 1

Day 002 of the year = intercalary day 2

Day 093 of the year = intercalary day 3

0 + 9 + 3 = 12 then 1 + 2 = 3

Day 184 of the year = intercalary day 4

1 + 8 + 4 = 13 then 1 + 3 = 4

Day 275 of the year = intercalary day 5

2 + 7 + 5 = 14 then 1 + 4 = 5


in standard (non leap) years of 365 days there are 5 intercalary days

3 + 6 + 5 = 14 then 1 + 4 = 5


in leap years of 366 days there are 6 intercalary days

3 + 6 + 6 = 15 then 1 + 5 = 6
