A year is the length of time required for Earth to complete one full rotation around the Sun; other planets in our solar system also experience years.
This calculator can help you quickly determine how many total years are between two dates. Input both start and end dates, and we will count both years and days!
Year on Earth
The year on Earth refers to the amount of time needed for our planet to complete one orbit around the Sun or calendar years for specific calendar systems.
The length of a calendar year varies according to different solar and lunisolar systems. In the Gregorian calendar, it begins on January 1 and concludes on December 31; on the Chinese lunar calendar, however, a lunar year typically lasts 354 days, with any discrepancies being known as leap days.
Astronomers use an alternative measure of Earth’s year, known as the tropical year. This timescale takes into account the passage of vernal equinox events; it differs from sidereal year by 20 minutes due to Earth’s axial precession.
Scientists have used data from other planets within the Solar System to establish an estimate for Earth’s age; this has revealed it to be approximately 4 billion years, which corresponds to roughly how long it took the Sun and planets to form out of a cloud of gas and dust.
At 20 UTC (3 p.m. CDT), our planet will reach its aphelion – or farthest point from the Sun – at 3 pm CDT today. Aphelion typically occurs in July when both Northern Hemispheres are enjoying summer while the Southern Hemisphere is in winter, though the distance between Earth and the Sun doesn’t determine seasons as much as its tilt relative to the orbit plane.
People born in 1928 or 1988 who are the Earth Dragon represent ambitious dreamers with complex work ethics who take great initiative. While they can be independent thinkers, they also possess great compassion towards both friends and family alike. Their ability to balance work and leisure gives everything their total effort.
Year on Other Planets
A year is the amount of time it takes for planets, satellites, or celestial bodies to complete one orbit around our sun or, in the case of extrasolar worlds, their host star. It differs from solar years as they focus on days that pass before starting fresh with a new year – something that relates to equinoxes (when planets tilt away or towards our sun).
A year on a planet varies according to its distance from the sun. Closer planets like Mercury must travel faster in order to avoid being drawn into it; as a result, their years tend to be short; those further away need longer to complete their orbits, hence longer years.
As well, the length of a year on any planet depends on whether or not its seasons vary significantly from those on Earth. Jupiter, for instance, experiences three-year-long seasons due to an axial tilt slightly less than Earth’s, while Saturn experiences seven-year-long ones due to an increased inclination compared with Earth. Neptune experiences seasons lasting 164.8 Earth years due to being so far from the sun.
Along with these factors, a planet’s day length and year length can also vary based on its orbital period. As a general rule, planets with shorter orbital periods tend to have longer days compared with planets with greater ones – the exception being Venus, which boasts both short orbital periods and relatively rapid axial rotation but has rather long days due to this.
Years Between Two Dates
When trying to determine how long ago something took place, you can use the number of years between two dates as an indicator. Subtract one from another using the year number – so if the current date is 2022 and its previous one was 2013, then 35 years have elapsed between them.
If you don’t know the year numbers for both dates, dividing by 12 will help you estimate their number of years; 30 months is equal to 2.5 years, for example.
Calculators are handy tools for pinpointing the number of years between two dates. Available online, these calculators allow you to calculate in decimal form how much time has passed between dates; additionally, they may show this period in other units such as months, weeks, or days.
Calculators make measuring periods easy: enter the start date and end date of what you wish to measure, and the tool will calculate how many years have elapsed between those dates. You can adjust settings if necessary – such as including leap years. Our DOB age calculator also makes this task simple!
How Old is Someone Who Was Born in February 1988?
If you were born in February 1988, then you are currently 35 years old according to the internationally used Gregorian calendar. This number is calculated using 12 months corresponding to each year in a common era, with 366 days in leap year being added on top, so your actual age now would be 35 plus 1 (leap year).
At your birth on February 23rd, 1988, Tuesday was the day of the week, and Libra was the astrological sign. Tuesdays are named for dies Martis, which in Latin means the “day of Mars,” which represents war, faithfulness, and marriage – also associated with this date as it commemorates both events!
Use our online age calculator to discover your current age. Just enter your date of birth and press ‘Calculate’; it’s that simple! From there, you’ll be able to see how many total years remain until your next birthday; plus, the calculator provides both decimals and whole numbers formats so you can choose how you would like yours displayed; for those interested in Roman numerals, select that option as well!
