Time

A gigayear is equivalent to one billion years. This means that a gigayear is a much larger unit of time compared to a regular year. To put it into perspective, there are one billion years in a gigayear, making it a significantly longer period of time.

John Harrison is credited with inventing the first marine chronometer in the mid-18th century. His invention greatly improved navigation at sea by providing an accurate way to determine longitude.

Sunset was 6:47 pm ET on September 27 2008 in New York.

A year is defined as the time it takes for the Earth to complete one orbit around the Sun, which is approximately 365.25 days. This is why we have leap years every four years to account for the extra quarter day.

people still use sundial. they also use them in gardens as garden features for more info on sundials visit the site below it gives heaps of info!!! http://en.wikipedia.org/wiki/Sundial people still use sundial. they also use them in gardens as garden features for more info on sundials visit the site below it gives heaps of info!!! http://en.wikipedia.org/wiki/Sundial

There is an average of 31556952000 milliseconds per year.

Your 1 kilometer equals 3.24077649 x 10-14 parsecs. And your second equals 3.16887646 x 10-8 years. Converting kilometers/second to parsecs/year involves multiplying by 3.24077649 x 10-14 and dividing by 3.16887646 x 10-8 to get your answer. Or do that bit of math in advance and then just multiply by 1.022689439 x 10-6 to get your answer. Make sure you have your beginning figure in km per one second. Your answer will appear in parsecs per one year, or just parsecs per year.

Correct spelling is 'millisecond'

There are 31556925993.6 milliseconds in a regular year.

To read time on a sundial, note where the shadow falls on the dial. The time is indicated by the position of the shadow on the numerals or marks that correspond to the current time. Sundials work by tracking the movement of the sun throughout the day and are most accurate when the sun is directly overhead.

12:00 PM is noon - daytime. 12:00 AM is midnight - nighttime.

The twilight hours of any given location are subject to change depending on the time of year; twilight hours during the winter will be different compared to twilight hours during the summer. On average, the summer twilight hours in Florida tend to be between the hours of 5:15am to 6:45am in the morning and 8:20pm to 9:50pm in the evening.

It cannot be used to tell the time of the day. It can only be used to tell the time interval that has passed. And if the flame is blown out, it doesn't work at all.

The new millennium began on January 1, 2001, not in 2000 as many believed. This is because there was no year 0 in the Gregorian calendar, so the year 2000 was the last year of the 20th century, not the first year of the 21st century.

A new day begins at 12:00:01 AM. What would actually be one second after midnight, or 00:00:01 military time.

Sundials are not as accurate as modern timekeeping devices due to variations in the position of the sun throughout the year and changes in daylight saving time. They also rely on clear skies and sunlight, so they are not effective during cloudy or nighttime conditions. Additionally, sundials can be impacted by shading from buildings or trees, affecting their functionality.

There are 87,600 hours in 10 years (365 days/year * 24 hours/day * 10 years).

Shadows look very long during sunrise and sunset when the sun is low on the horizon. This is because the angle of the sun's rays hitting objects creates longer shadows.

the earth rotates while moving around the sun. this be said, it wakes a day to revolve fully around the sun. while the earth is rotating, the angle of the sun changes, this has been learned a while ago, then we have sundials.

12 PM is noon. 00:00 AM is midnight.

But for a considered opinion, see the link below...

The first methods for telling the time relied on the movement of the sun across the sky. When the sun was directly overhead it was the middle of the day, or 'noon' and when it was on the horizon, it was early morning or early evening, depending if it was in the east or the west. However, this method was not very accurate, but nevertheless, it has been used for countless years, from early man, right though to today.

There are also sun dials, where the movement of a shadow across a graded disc corresponds to a certain time.

The length of day and night on Earth varies depending on the time of year and the observer's location. At the equator, day and night are each about 12 hours long. As you move towards the poles, the length of daylight and darkness can change significantly, with areas near the poles experiencing periods of 24-hour daylight or darkness.

The sidereal day is the period of Earth's axial rotation. It's the same at

every place on Earth on every day of the year.

It's 23hours 56minutes 4.1seconds long. (seconds rounded)

When planning a trip across several time zones, consider the time differences between each location to adjust your sleep schedule gradually. Allow yourself time to acclimate to the new time zone upon arrival by exposing yourself to natural light and staying hydrated. Make sure to pack necessities like a sleep mask, earplugs, and medication if needed to help with jet lag.
