Because they are useful for predicting the future.
Primitive people in the tropics have no real need for calendars; the weather doesn't change all that much from day to day. In the temperate zones, it's important to know when to plant, and when to harvest, and when to expect recurrent events.
One of the earliest calendars we know of was used to keep track of the seasons along the Nile River in Egypt; if you knew approximately when the Nile floods would occur each year (and they are fairly predictable!) then you knew more or less when to move to higher ground and when it might be safe to return.

What word means an instrument to measure time?
Many different instruments are used to measure time. It all depends upon the scale of time you are measuring. Clocks, stop watches, chronometers, sundials, and calendars are just a few. if you just say in simple manner it's clock or watch.
Where can one buy tide clocks?
A tide clock is a special clock that keeps track of the Moon's motion around the Earth. These types of clocks may be purchased from Amazon, Tidal Clocks and Coastal Tide Clocks.
Did they set sun clocks and water clocks back?
Sun clocks were adjusted by moving the position of the gnomon to account for the changing angle of sunlight, while water clocks were recalibrated by adjusting the flow rate of water through the mechanism.
What reason the atomic clocks used in global positioning system?
For the simple reason that atomic clocks are highly accurate - usually only gaining or losing one second over thousands of years. High accuracy is vital in GPS systems - otherwise the maps would be out of alignment as you travelled. As an example - One of the most recent atomic clocks constructed in 2010 is reckoned to only gain or lose less than a second in over a billion years !
Do clocks use magnetism?
Some clocks, especially those with mechanical movements, may use magnetism in their design to regulate or control the timekeeping mechanism. For example, some clocks may use a magnetic balance wheel or electromagnetic coils to help keep time accurately. However, quartz clocks and digital clocks typically do not rely on magnetism for their operation.
Why did man develop clocks and calendars?
To keep track of time.
Why the positions of earth and the sun were used to develop calendars and clocks?
becuz their from sunrise to sun down is considered a day and 24 hours on the clock is one day and one day contruibutes to the calender.
Why were the positions of the sun and Earth used to develop clocks and calendars?
becuz their from sunrise to sun down is considered a day and 24 hours on the clock is one day and one day contruibutes to the calender.
Is there a clock available that automatically sets for daylight savings?
Yes the one on your computer does that along with many LCD clocks with calendars.
How do human organize time?
Humans organize time using various methods such as calendars, clocks, and schedules. Calendars help track days, weeks, months, and years, while clocks measure time in hours, minutes, and seconds. Schedules help individuals plan and allocate time for different tasks and activities.
Do time and date on computers change automatically?
Yes. Computer calendars and clocks regulate themselves, even recognizing daylight savings time.
What are Daily life applications of real numbers?
There are many examples of daily life applications of real numbers. Some of these examples include clocks and calendars.
How does math influence our daily lives?
You need to know math in order to make purchases in your everyday life. Also math is important when using calendars and clocks.
Which is used for our clocks Sidereal or solar day?
Solar day is typically used for our clocks and calendars, as it is based on the Earth's rotation relative to the sun. Sidereal day, on the other hand, is based on the Earth's rotation relative to distant stars.
How do we measure time and what are the different methods used for tracking the passage of time?
Time is measured using various methods, including clocks, calendars, and astronomical observations. Clocks, such as analog and digital clocks, measure time in hours, minutes, and seconds. Calendars track time in days, weeks, months, and years. Astronomical observations, like the movement of celestial bodies, help measure longer periods of time, such as seasons and years. These methods work together to help us track the passage of time accurately.
What is a leap minute?
A Leap Minute is a minute that is added or removed according to what's needed to keep our clocks and calendars in synch with the movement of our planet and the sun. The movement of the Earth around the Sun, and around its own axis, doesn't match up exactly to our clocks and calendars. To prevent the error from growing year after year, Leap days, leap hours, leap minutes, even leap seconds, are regularly added to keep everything in synch.
What is a complicated antique clock called?
A complicated antique clock is often referred to as a "horological masterpiece" or simply a "horological clock." These clocks typically feature intricate mechanisms, such as multiple gears, complications like moon phases or perpetual calendars, and elaborate designs. Collectors and enthusiasts value them for their craftsmanship and historical significance. Notable examples include skeleton clocks and astronomical clocks.
