Sundials work by using the sun's position to cast a shadow onto a marked surface, such as a calibrated plate or ground. As the sun moves across the sky, the shadow changes, allowing people to tell time based on the position of the shadow in relation to the markings. The angle of the shadow indicates the time of day.

12 am is called midnight because it is the point at which 12 hours have passed since noon (midday) and the start of a new day. The term "midnight" signifies the middle point of the night, with "mid" meaning middle and "night" referring to the time of day when it is dark.
Night typically starts around sunset, which is when the sky begins to darken and the sun is no longer visible. Night officially begins when the sun has fully set and darkness settles in. This time can vary depending on your location and the time of year.
Post Meridiem is PM. It is Latin for "after noon". For example, 1:30 PM.

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.
What term would mean 1 billion years?
We'd probably use the term 1 gigayear to mean 1 billion years (in the U.S.). The prefix "giga" means 1,000,000,000 or, if you prefer, 106 units of something. The gigayear is a billion years, just the the gigaHertz is a billion Hertz (or cycles per second). Also note that we use a "big" G to represent giga. A Gyear is a gigayear or a billion years.
Many consider an Eon to be a billion years

How to convert kilometers per second into parsecs 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.

How do you read time on a sun dial?
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.
