What happened during 1582 and 1592?

Answer 1

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.
