## Lunar Standard Time

Suggested by LunarClock.org, the concept of the Lunar Calendar and Standard Time, or LST for short, is a time reckoning that is similar to terrestrial clocks, like UTC, but adapted to fit the periodicity of the Lunar day.

The basis for the LST is the Lunar second, which is defined as 0.9843529666671 Earth seconds. LST then works pretty much like a terrestrial clock; a minute is 60 seconds and an hour is 60 minutes. 24 hours make up a "cycle", and 30 cycles make up one Lunar day. There are 12 days in the Lunar year, named after the twelve first men to set foot on the Moon.
