A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
The planetary hours are an ancient system in which one of the seven classical planets is given rulership over each day and various parts of the day.

In physical cosmology, the age of the universe is the time elapsed since the Big Bang: 13.8 billion years. [1] Astronomers have two different approaches to determine the age of the universe . One is based on a particle physics model of the early universe called Lambda-CDM , matched to measurements of the distant, and thus old features, like the ...

Such a day may be called a calendar day. A day is commonly divided into 24 hours, with each hour being made up of 60 minutes, and each minute composed of 60 seconds.
Swift jet streams sculpt and stretch the clouds into long bands. Cyclonic storms on Jupiter can last for years because the gas planet doesn’t have a solid surface, which can slow storms down ...
