Mainly by the moon and stars. Obviously this was rough and ready for most people but because there was far less light pollution and people were more knowledgeable about the night sky in general most adults would have been able to estimate the time to within 1 hour4fyjjyý
The star clock was invented to track the movement of stars and other celestial bodies across the night sky, allowing people to tell the time at night before the invention of mechanical clocks. It was used by ancient civilizations for navigation, astrology, and timekeeping.
The first mechanical alarm clock was invented by Levi Hutchins, of New Hampshire, in the United States, in 1787. This device he made only for himself however, and it only rang at 4 AM, in order to wake him for his job.
What would the world be like if clocks weren't around? For one thing, the world would be a lot more unorganised because schools, jobs, social gatherings and things like that all rely on them. If they weren't invented people would be late for things and they wouldn't be able to get up in time for school, jobs etc. Not getting to places can cause stress and worries because if it were a big job interview, you would stress about being late of course. clocks heap everyone in every single way. people use clocks to much for their own good. clocks have been used for good and bad but most of the time good.
The shadow of the sun on sundials changes throughout the day as the sun moves across the sky. This allows one to estimate the time.
Without clocks, people would likely rely more on natural cues like the position of the sun to determine time. Schedules and time-sensitive activities would be more challenging to organize and coordinate. Communication and travel across different regions would also be more complicated without a standardized measure of time.
Some common objects people in the past used to measure time include sundials, water clocks, hourglasses, and candle clocks. These were effective tools for tracking time before the invention of mechanical clocks and watches.

Before electricity, people made mechanical clocks that were powered by weights or springs. These clocks used gears, escapements, and pendulums to keep time accurately. Sundials and water clocks were other types of timekeeping devices used before the invention of electricity.
Clocks. Sundials.
Before plastic was invented, clocks were typically made out of materials such as wood, metal, glass, and ceramics. Wooden clocks were common and intricate designs were often carved into the wood. Metal clocks were also popular, with brass and iron being commonly used for clock casings. Glass was used for clock faces and coverings, while ceramics were used for decorative elements.

People determined that there waas a need to keep track of time more accurately than with a sundial, or hour glass. So a mechanical device was invented. There are many applications that require accurate time keeping. For instance navigation of sailing ships greatly improved when the clock was adapted to a moving platform.
The first water clocks were made out of pottery or metal containers with calibrated markings. Water dripped or drained out from a small hole at a steady rate, allowing people to measure time based on the water level.
Alarm clocks are useful to keep people on track. Uses for alarm clocks or timers - waking up people, used for cooking.
