Lunar Standard Time (LST)
Now that you are familiar with the concept of Lunar Standard Time, there are a number of date and time formats that can be used.
The LST symbol ∇
To denote that a date or time is Lunar, we use the inverted triangle (which is an ancient symbol representing Luna - the feminine principle).
Many fonts support this symbol, as it is a part of notation in physics and mathematics, i.e. the Hamilton operator (▽, html code ▽
, and Unicode 25BD
and the nabla symbol (∇, html code ∇
, and Unicode 2207
). In a pinch one could simply use the capital letter V instead.
So, dates in Lunar reckoning (year, day, cycle) should always be suffixed by ∇ and likewise LST time should use the ∇ prefix.
The LST standard notation
This is Year-Day-Cycle ∇ Hour:Minute:Second. For example, this page loaded at 51-01-01 ∇ 00:21:10.
The date and time are separated by the Lunar symbol (∇), and so it is a suffix to the date and a prefix to the time, as explained in the above.
The LST date format
Just stating the date part would be simply chopping of the time value. So we'd have 51-01-01 ∇, and the ∇-suffix indicates that this is Lunar reckoning.
The day number could be replaced with its name of course, and since we are now in day 1 we could write 51-Armstrong-01 ∇
or perhaps simply Armstrong 1st
Other examples of date formats, typically for denoting partial date references, include 1 ∇ (meaning Lunar cycles), and 51Y 1D ∇.
The simple rule being; if there's an ambiguity, use Y/D/C to denote what is what.
The LST time format
Just stating the time part would be simply chopping of the date value. So we'd have ∇ 00:21:10, and the ∇-prefix indicates that this is a Lunar time code.
Other examples of time formats, typically for denoting smaller time-frames, include ∇ 0 (meaning Lunar hours), and ∇ 21m 10s.
The simple rule being; if there's an ambiguity, use h/m/s to denote what is what.
What about dates before 1-01-01 ∇ 00:00:00?
Such dates would simply be prefixed with a minus sign (-). For example, ten seconds before Armstrong stepped onto the Moon would be -1-01-01 ∇ 00:00:10.
14 cycles before Armstrong would be -1-01-15 ∇
