**Exact answer: 6 years**

Time is an illusion, famously stated by Albert Einstein. It is a measure of consistent change happening in one’s surroundings. Instruments such as clocks and calendars are used to measure time.

In ancient prehistoric times, people first started to wonder about time by observing the movements around stars and planets. Humans first recorded the different phases of the moon some 30,000 years ago. The accurate measurement of minutes was made only 400 years ago after several attempts and research.

The instruments used in Horology, such as clocks and calendars display similar features and are the result of advancement. They consist of repetitive, constant marks to calculate the passage of time. They fundamentally act as measures of time increment and accurate display.

**How Long Are 72 Months?**

A year consists of 12 months, and a month is made up of 30-31 days, with an exception of February, which has either 28 or 29 days. 72 months in terms of years, is 6 long years. Since each year has about 365 days, 72 months in terms of days is 2190 days.

Each day is made up of 24 hours, so 72 months in terms of hours is 52,600 hours. An hour is made up of 60 minutes and a minute is made of 60 seconds. Therefore, 72 months in terms of minutes and seconds is 32,56,000 minutes and 18,93,60,000 seconds respectively.

Every month consists of 4 weeks. Thus, 72 months is made up of almost 314 weeks. In terms of a newborn baby, turning 72 months old would mean a significant time has passed and the child has grown up to be a 6-year-old. The newborn baby after 72 months will know how to talk, walk, and even go to pre-school, unlike its initial state.

In summary:

Months | Time Unit |

72 | 6 years |

72 | 2190 days |

72 | 314 weeks |

72 | 56,200 hours |

72 | 32,56,000 minutes |

72 | 18,93,60,000 seconds |

**Why Are 72 Months So Long?**

According to the Gregorian calendar, each year is divided into 12 months. Each month is either 28, 30, or 31 days long in a common year with 365 days. In a leap year, which occurs every four years, the year has a total of 366 days, because of the presence of an extra day in February.

The Gregorian calendar has the following 12 months:

- January – 31 days
- February – 28 days in a common year, 29 days in a leap year
- March – 31 days
- April – 30 days
- May – 31 days
- June – 30 days
- July – 31 days
- August – 31 days
- September – 30 days
- October – 31 days
- November – 30 days
- December – 31 days

There are 4 months of 30 days and 7 months of 31 days in a year according to the Gregorian calendar. A year is either 366 days or 365 days long depending on whether it is a common year or a leap year. 4 weeks make up a month and 48 weeks add up to become a year.

A week has 7 days and a day consists of 24 hours, each again containing 60 minutes of time. 60 smaller units of time, called the seconds, together make up one minute. Therefore, 72 months can be expressed in various time units.

Some units smaller than 1 day:

- 1 day is equal to 24 hours
- 1 hour is equal to 60 minutes
- 1 minute is equal to 60 seconds

In simple terms, 72 months together form 6 years and is made up of 2190 days. It is a significantly long period in a person’s life as a lot of things can occur during this period of one’s life. One can witness a teenager turn into a young adult during these many years.

**Conclusion**

Time is a measurement of constant change happening all the time around us. It is measured in different units such as years, months, days, hours, minutes, and seconds, with the help of instruments such as a calendar and clock. Time is irreversible and it waits for none.

72 months is six times 12 months, which adds up to become 6 years. It can also be expressed in smaller units of time such as days, hours, minutes, and seconds. Smaller units such as nanoseconds, microseconds, etc can also be used to express 72 months.

The theory of special relativity clearly states that gravity curves space and time. The stronger the gravitational pull, the slower would be the passage of time. This proves time is relative and it is the reason why astronauts in International Space Station age slower than humans on Earth.
