New Earth Time

New Earth Time is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand New Earth Time rather than just read about it. In short: New Earth Time (or NET), also called degree time, is an alternative naming system for measuring the time of day proposed in 1999. In NET the day is split into 360 NET degrees, each NET degree is split into 60 NET minutes and each NET minute is split into 60 NET seconds.

Key takeaways

  • New Earth Time belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect New Earth Time to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of New Earth Time from memory before moving on to harder problems.

Reference excerpt

New Earth Time (or NET), also called degree time, is an alternative naming system for measuring the time of day proposed in 1999. In NET the day is split into 360 NET degrees, each NET degree is split into 60 NET minutes and each NET minute is split into 60 NET seconds. One NET degree is therefore equivalent to four standard minutes, and one standard hour is equivalent to 15 NET degrees. NET is equivalent to the UTC read from a 24-hour analog clock as the clockwise angle past midnight of the hour hand. For example, noon is 180°0′0″ NET and at that time the hour hand is pointing straight down forming a 180° angle when measured from the top, at midnight. A full circle is 360 degrees and one NET day.

History New Earth Time was invented on 15 September 1999 by Mark Laugesen from Auckland, New Zealand. The rights to the name New Earth Time (or NET) and slogan "360 degrees of time" are novel and owned by degree NET Ltd. Similar ideas for unifying time measurement across the globe include Swatch Internet Time, another rebranding of UTC+1.

Worked examples

Example 1 — a first encounter with New Earth Time

Start with the simplest possible case. Write down what New Earth Time claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to New Earth Time before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about New Earth Time ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of New Earth Time

In research
New Earth Time appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses New Earth Time in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
New Earth Time is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1999 works, Time measurement systems, so understanding it makes those chapters shorter.
In everyday life
Look for New Earth Time outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is New Earth Time in simple terms?

New Earth Time (or NET), also called degree time, is an alternative naming system for measuring the time of day proposed in 1999. In NET the day is split into 360 NET degrees, each NET degree is split into 60 NET minutes and each NET minute is split into 60 NET seconds.

Why does New Earth Time matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study New Earth Time?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on New Earth Time.
