[edit] Standard Earth Year

Standard unit of time measurement on Earth determined by the average length of the planet's solar orbit. The year is divided up into 365.2425 planetary rotations which are in turn grouped into twelve months, most lasting 30 or 31 days. Although Mars still uses the Standard Earth Year for timekeeping, the orbital period of Mars is equal to 1.88 Earth Years and as such local seasonal cycles, such as the Martian winter are measured from that period.

[edit] Cycle

Many worlds use the term 'cycle' to refer to their solar years, however some also use the term to refer to much smaller measurements of time, sometimes leading to confusion.[1][2][3]

  • A Minbar day lasts 20 hours and 47 minutes.[6]

  1. Grail (episode) - Deuce gave jinxo "300 cycles" to pay up. Given the timescale of the episode, in this instance a cycle probably equates to 1 minute. Thus 300 cycles equals 5 hours.
  2. The Geometry of Shadows - Ivanova confused a cycle for a Drazi Week, when it was in fact a year
  3. Babylon Squared - in July 2258 Delenn said it had been 10 cycles since the death of Dukat.
  4. By Any Means Necessary - 12.2 earth years equals 10 Narn years
  5. A View from the Gallery - G'Kar mentions the bombings lasting 31 hours a day.
  6. To Dream in the City of Sorrows - Explicitly stated. Sinclair noted how it caused him some problems with his sleep pattern.
