History
After the New Era event, Rhapsody Azadivar made some changes to the calendar to make it more compatible with the history of the world. He added year designators, months, and seasons to the calendar to make it easier to record events that happened before its epoch. He is known as the inventor of the modern Jnan Calendria.

Epochal date
The calendar's epoch (the first year) corresponds to the first day of the month when the Magnificent Advent event (Basokuh Goronush "𐎖𐏕𐎣𐏒𐎹𐏕𐏃𐏐𐎰𐏒𐎏𐏒𐎴𐏒𐎿") took place in the Prinos region, which is also the day Kylorne has been launched.

Days per month
A year in Jnan Calendria has 384 days, which separated into 16 months with 24 days.

New Year's Day
The first day of the year in the calendar is called Sprout Day (Sabzehruz "𐎣𐎂𐎖𐎌𐏓𐏃𐎏𐏒𐎌"). In Riava, there is no major ceremony for New Year's Day at the national or international level, but it's a national day-off. The military of Riava shoots 16 cannons to mark the start of the year. Families and friends gather together to celebrate the new year, and at the end of the day, some families plant a tree to honor the arrival of Spring (Bahar "𐎖𐎂𐏃𐏕𐎏").

However, every five years, Riava gives a month-off and hosts a grand ceremony for a month at the beginning of the year to celebrate the arrival of Niada, the goddess of knowledge, who promised to return to the world every five years on the 21st day of the year. During this time, many politicians are invited to Riava, festivities take place, and all institutions in Riava hold gatherings and meetings.
