What Year Is It

What Year Is It?

Whether you’re checking the date on your phone or computer, it’s likely that you already know what year it is – but have you ever wondered how we came up with the current calendar system? Or why some parts of the world use a different year than others? In this informative article, we’ll explore the history of our modern calendar system and answer some common questions about how we keep track of time.

The History of the Modern Calendar System

The calendar system used in much of the world today is called the Gregorian calendar, named after Pope Gregory XIII who introduced it in 1582. Prior to this, the Julian calendar was used – a system created by Julius Caesar in 46 BCE that featured a 365-day year and an additional day every four years, known as a leap year.

However, the Julian calendar was flawed in that it calculated a year as being 365.25 days long instead of the more accurate 365.2425 days. This seemingly small discrepancy led to a significant problem over time: the calendar was slowly but surely falling out of sync with the astronomical seasons.

To correct this, Pope Gregory XIII introduced a new system that involved skipping leap years on century years that were not divisible by 400. This adjustment brought the calendar almost perfectly in sync with the astronomical seasons and has been used ever since. The switch was not immediately embraced by all countries, and it wasn’t until the 18th century that it became the standard calendar system used across much of Europe.

Other Calendar Systems

While the Gregorian calendar is the most commonly used calendar system in the world today, there are many other calendar systems that exist or have been used throughout history.

For example, the Islamic calendar is a lunar calendar that is based on the observation of the moon, making each year 11 days shorter than the Gregorian calendar year. This means that Islamic holidays and events fall on different dates each year, and that the Islamic calendar and Gregorian calendar will only coincide every 33 years or so.

The Chinese calendar is another lunar-based system that has been in use for over 4,000 years. It features a twelve-year cycle that is based on animal zodiac signs, with each year being associated with a specific animal such as the rat, ox, and tiger. The calendar also incorporates elements of the five Chinese elements – wood, fire, earth, metal, and water.


Q: What year is it in the Jewish calendar?

A: The Jewish calendar is a lunisolar calendar that is based on both the observation of the moon and the calculation of the sun’s position. The current year according to the Jewish calendar is 5781.

Q: Why are some countries behind or ahead of other countries in terms of the year?

A: Different countries use different calendar systems, which can result in different years. For example, Ethiopia uses the Ethiopian calendar, which is a solar calendar based on the Coptic calendar that has an additional leap year every four years. The current year in Ethiopia is 2013.

Q: Is the year 0 a real year?

A: No, the year 0 does not exist. The Gregorian calendar begins with the year 1 AD (Anno Domini), and there is no year 0 in between 1 BC (Before Christ) and 1 AD.


While the Gregorian calendar is the most commonly used calendar system in the world today, it is important to remember that it is just one of many different ways that people have tried to keep track of time throughout history. Whether you’re following a lunar-based system or a solar-based system, the goal is ultimately the same: to make sense of the passing of time and to mark important events and milestones.
