February 29 as a unique Day is a sense-forming core of the
LUXENDAR formalism. This calendar project is declared as a conceptual work and has philosopho-aesthetic planetary tasks.
February 29 demonstrates the evident time density and cannot be ignored by human communities any more if they call themselves informationally intelligent.
The naturally conditional time density obtained through February 29 and dictated by daily and orbital revolutions of planet Earth preserves the value potential for the next stage of futuristic aestheticism.
