Will California get rid of daylight saving? Only time will tell

by in News

Daylight saving time began at 2 a.m. today, so let’s take a minute to talk about time.

Assembly Bill 7

After a failed attempt to end daylight saving time in California in 2016, Proposition 7 passed with 59.75 percent in favor of ending daylight saving time in 2018.

It’s going to take time before daylight saving ends in the state. AB 7 needs a two-thirds vote by the Legislature and must be signed by the governor, then will need to be approved by the federal government.

The state government is expected to vote on AB 7 this month.

Benjamin Franklin

1784

While on diplomatic duty in Paris, Benjamin Franklin became the first to suggest shifting clocks forward in the spring and back in the fall to save money on candles.

1916

On April 30, Germany became the first nation to enact daylight saving time to conserve electricity. The Germans were fighting World War I. The British followed their lead and introduced “summer time” a few weeks later.

70

The approximate number of countries that observe daylight saving time. They have about one-quarter of the world’s population. Most countries near the equator have no need to change time for more daylight hours.

2007

Daylight saving time is extended from the first Sunday in April in the U.S. to its current length, beginning the second Sunday in March and ending the first Sunday in November.

Hours in the day

By springing forward the clock, we’ll lose an hour. This chart shows the average amount of time per day Americans of various ages spend in selected activities. The data refer to all days of the week and were calculated by the Bureau of Labor Statistics for 2016.

The long and short of it

With the clocks turning forward, you will lose 3,600 seconds of the day. Not much when you consider there are 86,400 seconds in a day.

The first clocks to have a second hand appeared in the 1750s.

Take an eon

In formal usage, eons are the longest portions of geologic time after what’s called an era. Less formally, an eon equates to 1 billion years.

Once in a blue moon

A blue moon happens on average about every 2.7 years. A seasonal blue moon is the third of four full moons in one season. The next seasonal blue moon is May 18.

The second of two full moons in the same month is also called a blue moon.

Just one zeptosecond

In 2016, researchers at the Max Planck Institute in Germany measured minute changes within an atom on the zeptosecond scale. It is the the smallest measurement of time ever recorded. How small? The number would be sitting 21 places behind the decimal point, or a trillionth of a billionth of a second.

time iconsIn a jiffy

A jiffy is a measurement in electronics, computing, astrophysics, and quantum physics. In physics, it is roughly the time it takes light to travel 1 centimeter in a vacuum, approximately 33.3564 picoseconds (a picosecond is one-trillionth of a second).

Fast as lightning

The bolt of lightning that moves upward travels at about 320 million feet per second, which is about one third the speed of light. Thunder is much slower and travels about 1,100 feet per second.

At the drop of a hat

Gravity accelerates at 9.8 meters per second, per second. A light object, such as a hat falling from about 6 feet, would travel approximately 7.67 meters per second and land in about .78 seconds.

In a heartbeat

The average heart rate is 72 beats per minute, when one heartbeat occurs every .83 seconds.
