In the old days, people lived their lives a whole lot differently than they do today. For instance, 100 years ago (876,000 hours ago to be precise), a 32-year old woman might already be a grandmother—and a 14-year old boy would likely be in the workforce! So…what about your own ancestors? Have you ever wondered what their lives were like? Show

What is my age?Age, in general, is the amount of time for which something existed. A person's age is the time that has passed from the moment they were born. The time before birth is called the gestational age (the age of a pregnancy is counted from conception). In most parts of the world, a baby starts life at 0 and becomes 1 year old on the first anniversary of their birth. However, in some countries (notably in Korea), age is counted differently. In the text, we'll use the most common system. Let's see how to use the age calculator to help you answer the question - "what is my age?". How old am I today? Ask the age calculatorHow old are you? The easiest way to answer this is to use the age calculator and let it calculate age from your date of birth:
The result will be exact if you choose "years/months/days." In this option, we assume that a month passes from the chosen day of the first month to the same day of the second month (e.g., 22.02 to 22.03). If you choose the "months" unit, we will assume that months have 30.4375 days (that's an average). In the "years" option, we assume a year has 365 days (we don't account for leap years). How old are you? Calculate age from the date of birthWe'll now learn how to calculate age from date of birth without help from the age calculator. Let's say it's 15.01.2021, and you were born on 5.12.2000. Let's time-travel and count:
How many days/weeks/months/... old am I?This age calculator includes various time units, so it can answer all the strange questions like "How many weeks old am I?", "How many seconds old am I?", "How many days old am I?", etc. To check your age in different units, enter your date of birth, make sure you have today's date in the second field, and set the desired unit in the last field of the age calculator. How old will I be in 2050?Counting age for future dates works the same as for past dates. In the age calculator, you need to change the default current date (the "Calculate age on" field) to the future date. Let's say you were born on 4.03.2005. If you're wondering, "How old will I be in 2050?":
Make sure to also check out our Lunar age calculator and find out your age according to the Chinese and Hijri calendars. If you were born in 1999, how old are you?If you don't know someone's exact date of birth, subtract the year of birth from the current year and the result will be the estimated age (you can be off by one year either side). For example, now it is 10.01.2021. Let's subtract years:
So, the answer to "If you were born in 1999, how old are you?" is: "In 2021, you'd be approximately 22 years old". However, if you were born after 10.01, you'd officially become 22 on your birthday. Until then, you'd be 21 in the eyes of the law. How many days are there in 15 years?If you're 15 and wondering, "How many days old am I?", enter your date of birth and today's date into the age calculator. Then choose "days" as the unit. If you want to convert 15 years to days, you can use our time unit converter or type into this age calculator two dates that are 15 years apart. For example, "Jan 1, 2000" and "Jan 1, 2015" are 5479 days apart. Example - "How old was I on this date......when I first learned that time is relative?" You've just found your diary in the attic, opened it on a random page, and read: "3.02.1978 Nothing will ever be the same again. I used to think that time is something like a line going from left to right on which we travel. I thought it was always the same, whoever and wherever you are. Today Mr. Brown (and I trust his knowledge) said that the faster you move, the slower time passes! 😮 " You've moved fast, but not fast enough. You've grown old, and it happened so quickly. You've started wondering, "How old was I on this date?". You don't have much time for calculations, so you turn to our chronological age calculator:
