## Why Are Dates Essential in Our Lives?

We cannot deny the importance of dates in our lives. Some important dates that I still remember are my birth date, when I graduated, when I got married, and the birth dates of my children.

Dates and events

Our lives are full of events, and dates are used to remember the time of a particular event. Maybe that event is pleasant or may not be suitable for your life.

Therefore, dates are essentialDates note a particular event because our history is recorded chronologically. So, dates help us compare one event with another. We can check whether that one event happened before another and examine the relationship between those two events.

## Dates to Mark the Periods in History

Dates are used to mark periods in history. However, historians can disagree with the start and end dates of a period. The people who lived in that period even had no idea that historians would remember them as the persons residing in that specific period in the future. Like the people living in Europe in 1922, they had no idea that they lived in "interwar years" because, at that moment, there was no clue that there would be World War II in the future.

### Dates and cultural identification

Dates are also crucial for a group's cultural identityJuly 4 is an important date in United States history, as it is American Independence Day. Therefore, each state or group of people has some dates that show their cultural identity.

### Chain of cause and effect

Even with the date, we see history as a chain of cause and effect. Some minor events lead to dramatic and significant changes that shake the whole world. Therefore, dates help us analyze when an event happened in the past and when its expected consequences will come.

When tracking historical events, it doesn't matter which calendar you use if you put them in the right sequence. Today, the Gregorian calendar is the most used in the world. It marks years as BC (before Christ) or AD (anno domini, i.e., "after the death of Christ"). However, various other timekeeping systems exist, including Hebrew, Islamic, and Chinese.
