Why was October 1582 missing 10 days? This is the Scientific Answer

LONDON – Missing 10 days in the month October The year 1582 on your phone is not due to a bug or error, but rather due to a calendar change that was made at that time.

Previously, most of Europe used the Julian calendar, which was introduced by Julius Caesar in 45 BC. This calendar has a slight inaccuracy, namely an excess of 11 minutes and 14 seconds per year. This causes the Julian calendar to be out of sync with the movement of the Sun.

In 1582, Pope Gregory XIII introduced the Gregorian calendar to correct these inaccuracies. This calendar has more precise rules for determining leap years, so that the difference with the movement of the Sun becomes smaller.

In order to make the transition to the Gregorian calendar smooth, 10 days in October 1582 were deleted. This period is known as the missing 10 days period.

So, people who went to bed on October 4, 1582, woke up on October 15, 1582. The calendar on your phone shows this exactly, by jumping from October 4 to October 15.

This calendar change was a significant event in history, and the “missing” 10 days in October 1582 is a reminder of human efforts to align time with the movement of the universe.
