Date Calculator

This date converter initially shows today's Date in the UCC Year and today's equivalent Gregorian Calendar date

You can then enter either a UCC Date or a Gregorian Date into the boxes shown, then click <Apply> and the converter will show the corresponding Date in the other Calendar

Date of Birth

If you'd like to know your Date of Birth in the UCC, enter your Gregorian DoB and click <Apply>

Your Age In Days

If you'd like to know your age in days, first clear the <days added:> box then click <set today's date>

Then, simply enter your birth date in either UCC or Gregorian formats.

The resulting minus figure shown in the <days added:> box will then be 'your age in days' today!


Entering & Selecting UCC Dates

The UCC Year

<day of month>

Each perennial Triad (month) has 30 Days (made up of 3 'Decan' Weeks of 10 Days)

Triads 1, 4, 7 & 10 can also accept a <day of month:> '0' selection - see below



The month numbers and names of each Triad follow the Western Tropical Zodiac as follows:





UCC Triad Months

1.ONE-Aries ♈

4.FOUR-Cancer ♋ 7.SEVEN-Libra ♎ 10.TEN-Capricorn ♑

2.TWO-Taurus ♉

5.FIVE-Leo ♌

8.EIGHT-Scorpio ♏

11.ELEVEN-Aquarius ♒

3.THREE-Gemini ♊

6.SIX-Virgo ♍ 9.NINE-Sagittarius ♐ 12.TWELVE-Pisces ♓

You can also select <month:> 0 for the Intercalary Days 'New Year's Day' and 'Leap Year's Day' (see below)

Select the appropriate UCC Triad Month from the drop down menu in the date calculator

(they are called 'Triad' Months because 'Triad' means "...a group or set of 3 related things..." and there are 3 Triad Months in each Quarter Season and each of them consists of 3 'Decan' Weeks)


Intercalary Days

New Year's Day

The Date for the 1st Intercalary Day, New Year's Day (Day 001) in the UCC, is Day 1 of Month 0.

e.g. to select New Year's Day for the year 13515 you would select <day of month:> 1, select <month:> 0 and enter <year:> 13515

The 4 Other Intercalary 'New Season' Days

The Dates of the 4 other Intercalary Days which mark the starts of each Quarter Season (Days 002, 093, 184 & 275 of the year - as shown in the graphic above) are always Day 0 of Months 1, 4, 7 & 10 respectively

e.g. for the year 13515:

 for 1st Season's Day (Day 002) select <day of month:> 0, select <month:> ONE-Aries♈, enter <year:> 13515

for 2nd Season's Day (Day 093) select <day of month:> 0, select <month:> FOUR-Cancer♋, enter <year:> 13515

for 3rd Season's Day (Day 184) select <day of month:> 0, select <month:> SEVEN-Libra♎, enter <year:> 13515

for 4th Season's Day (Day 275) select <day of month:> 0, select <month:> TEN-Capricorn♑, enter <year:> 13515

Leap Year's Day

In Leap Year's an extra Intercalary Day (Day 000) is inserted at the start of the year, so for this select <day of month:> 0 then select <month:> 0


UCC Year Numbers follow the 24,000 Year 'Great Year' Cycle
In the current Great Year cycle:
Year 0 equates to the year 11,502/11,501 BCE Gregorian
Year 11,502 equates to the year 1/2 CE
(There is no year 'zero' in the Gregorian Calendar)
Year 12,000 equates to 499/500 CE Gregorian
Year 13513 equates to the year 2012/13 Gregorian (the year the UCC was first published)
   There are 2 Gregorian years quoted in each example above because the UCC Year starts the day after the 'Nobenox' (North Bound Equinox) which takes place in March in the Gregorian Calendar, and ends on the following Nobenox
   So the UCC Year runs from circa March 21st to March 20th Gregorian
To fully understand UCC Year numbers see the Great Year page
Leap Years
Leap Years follow the Persian Leap Year Cycle of 8 Leap Years in a 33 Year Cycle
8/33=0.2424 and so gives the most accurate 'rounding up' - closest to the 0.2422 of a day fraction left over each year
To see which years are Leap Years in the UCC please see the 'Leap Years' page
