Leap years were first implemented in the Gregorian calendar in 1582.
International Women's Day, 1917, in St. Petersburg/Petrograd, Russia, marked the start of the Russian Revolution. The dates were March 8th to the 12th on the Gregorian calendar. This is the current common calendar. In Russia at the time, the Romanov dynasty had never implemented the change to the Gregorian calendar from the Julian calendar, as most all other countries had already done. There is a discrepancy between the two systems, which at the time caused the Julian calendar to be 13 days behind the Gregorian calendar. So according to Russian calendars at the time, the dates of the uprising were February 23rd to the 27th on the Julian caledar. This being the case the event became known as the February, rather than the March Revolution.
The Gregorian calendar, the most commonly used calendar today, was first introduced in October, 1582 as a reform of the Julian calendar, which had been in use since the fifth decade B.C. The start date (the year 1) was believed to be the year of the birth of Jesus of Nazareth, but that calculation has been known for centuries to be incorrect.
Hindu calender starts from 3102BC since then 5111 years passed by. Hindu myth says after 5000 years the present kaliyuga(era) will end and a golden age will start. if this is true the golden age has already started based on lunar Hindu calender years. there is nothing special about the year 2012.
In 1582, the Gregorian calendar was introduced by Pope Gregory XIII to reform the Julian calendar, correcting inaccuracies in the calculation of leap years and aligning the calendar with the seasons. This change led to the loss of ten days in October of that year, as countries transitioned to the new system. In 1592, Japan experienced the start of the Sengoku period's end, characterized by significant military conflicts and political consolidation under the Tokugawa shogunate, which would ultimately lead to the unification of Japan in the early 17th century. These events marked significant shifts in both European and Japanese history.

The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
The adoption of the new calendar, such as the Gregorian calendar in 1582, was implemented by Pope Gregory XIII to correct inaccuracies in the Julian calendar. It was gradually accepted by different countries over time to align with the seasons and improve accuracy in tracking time.
The Gregorian calendar is a solar calender, that was first used in 1582. This is where the start of leap year came into play. This is also how they began to determine the date of Easter.

The current Gregorian calendar was introduced in October 1582 by Pope Gregory XIII. It replaced the Julian calendar, which had been in use since 45 BC. However, not all countries adopted the Gregorian calendar at the same time; for instance, Great Britain and its colonies switched in 1752. Today, the Gregorian calendar is the most widely used civil calendar around the world.

Hanukkah starts on a different day each year because it follows the Hebrew calendar, which is lunar-based, rather than the Gregorian calendar, which is solar-based. Specifically, Hanukkah begins on the 25th of Kislev, the ninth month of the Hebrew calendar, resulting in its date varying between late November and late December in the Gregorian calendar. This shift occurs because the Hebrew calendar is about 11 days shorter than the Gregorian calendar.
To read a Julian calendar date, you need to understand that it counts days from the start of the Julian calendar, which began on January 1, 4713 BCE. Julian dates are often expressed as a continuous count of days, meaning they don't divide the year into months or weeks like the Gregorian calendar. To interpret a Julian date, you can convert it into the Gregorian calendar by adding the appropriate offset, which is typically 13 days for dates after the introduction of the Gregorian calendar in 1582. Various online converters and software can assist in making this conversion easily.
