Jakobian calendar

The Jakobian calendar system, also known as the Jakobian date system, is a system used to define time. The existence of this particular calendar system is one of the many calendar systems used by various nations in the multiverse, due to sheer multi-dimensional nature of the multiverse.

About
The notion of the system largely relies on the idea of "Two Years Per International Cycle, One Year Per Domestic Cycle", also known as the "2 per World Cup" cycle in many nations. It is not really known who was the first one to give a name to this time system. Based on the system, the first football World Cup begins in 1930, and that qualification has begun the year before. This means that by calculation, World Cup 81 occurs in the year 2090, and the upcoming World Cup 86 will occur in the year 2100. Alternatively, it could be based on the IFCF competition seasons, with the first season occurring in 2095.
