About Calendars and Measuring Time

Artifacts from the Paleolithic suggest that ancient people used the moon to measure time with lunar calendars, which consisted of 12 or 13 lunar months (354 or 384 days).

The seasons quickly drift in a calendar based solely on twelve lunar months without adding extra days or months. To make up for the difference between a full year (now known to be about 365.24 days) and a year of twelve lunar months, some years in lunisolar calendars have a thirteenth month added to them.

The numbers twelve and thirteen have been significant in many cultures due to their relationship with the months and years. Another calendar type was developed in Mesoamerica, particularly in the ancient Mayan civilization. These calendars were based on religion and astronomy, with a year consisting of 18 months and each month consisting of 20 days. Additionally, there were five epagomenal days at the end of the year.

In 45 BC, Julius Caesar introduced reforms that changed the Roman world's calendar to a solar one. However, the Julian calendar had a flaw, as its intercalation still allowed the astronomical solstices and equinoxes to progress against it by approximately 11 minutes every year.

Pope Gregory XIII introduced a correction to fix this issue in 1582. Although different nations took centuries to adopt the Gregorian calendar, it is now the most commonly used calendar worldwide.

The Kingdom of Unixploria uses the Gregorian calendar but keeps an older Norse calendar to honor our Viking ancestors. Like the Calendar for Diversity and Inclusion, our Norse Calendar offers another perspective: a culturally homogenous calendar where nature sets the tone for festivities and seasons. We need both the global and the local in our modern times, and we need both a multinational, tolerant outlook and a culturally homogenous heritage to keep our feet on the ground.

Calendar for Diversity and Inclusion

Calendar for Diversity and Inclusion

We constantly reassess our role as cultural mediators. Over the past year, one of our goals has been to be more inclusive and show the riches of minorities in terms of culture and customs.

We sincerely believe that the world will become more prosperous with increased knowledge. Our faith and culture are no less valuable because we also highlight others. It is time to embrace humanity without sacrificing our own unique identity.

We want to learn from others and work in a spirit of tolerance and human unity. It is no coincidence that we have chosen the theme "diversity and inclusion."

Diversity without inclusion is just individual pieces of the puzzle; together, these pieces become a beautiful canvas. The canvas of human diversity grows with increased awareness, leading to a more tolerant society.

We welcome you to learn more about customs that may not be traditionally Unixplorian but are most definitely human.

Norse Calendar

Norse Calendar

The Vikings' description of days and months reveals their beliefs and the challenges and opportunities each season brings.

The Norse year reflected the changes in seasons, such as the height of the sun in the sky, availability of food, and fertility. The year was divided into two halves, namely summer and winter. People's ages were counted by the winters they had lived through. It is believed that the "New Year" started on April 14, also the first day of summer.

In ancient times, the year was divided into moon phases, from new moon to new moon or full moon to full moon. However, counting days was not always accurate in Scandinavia because the nights were quite bright, making it challenging to observe the moon.
