Moon Phase

From HorizonXI Wiki

Moon Phase Calendar

As the moon orbits Vana'diel it goes through phases. Each phase refers to how much of the moon's face is illuminated by Vana'diel's Sun. As the moon moves through these phases it is described as either "Waxing", the moon is getting visibly "bigger",as it heads towards Full Moon or "Waning", the moon is getting visibly "smaller", as New Moon approaches.

The moon phase affects certain aspects of Vana'diel, as well as some pieces of equipment. It is also rumored that moon phases affect certain luck-based elements of the game, such as the chances of getting item drops off an enemy, or crafting results. (See below)

You can check the current moon phase, as well as its percentage, by using the /clock command. This command also toggles the display of the game clock on your screen. To keep the clock on your screen, use the /clock command again, or use "/clock on" instead.

Each full lunar cycle (lasting from 0% New Moon to 100% Full Moon and back to 0% again) lasts for 84 game days (3 days, 8 hours, 38 minutes, and 24 seconds, Earth time). Vana'diel has 12 distinct Moon Phases.

On an interesting side note, the moon's face will be tinted the color of the current day as the days change (i.e. on Firesday the moon will tint red and on Windsday the moon will tint green).

Another interesting side note; due to tidal locking, Vana'diel's moon appears to orbit in synchronous rotation around the planet, showing the same face to Vana'diel at all times. This behavior is not unlike what is found on the moon orbiting the distant planet Earth.

    Moon in Real Time

    Each 1% of moon phase is equivalent to 24 minutes and 11'52 seconds of real world time.
    To calculate how many minutes moon needs to be in a percentage you want to know, just need to multiply the difference of percentages by 24.192.
    To know the percentage difference you have to take in count:

    • When moon is waxing:
      • If desired percentage is greater than current: difference = desired - current.
      • If current percentage is greater than desired: difference = 200 - current - desired.
    • When moon is waning:
      • If desired percentage is lower than current: difference = current - desired.
      • If current percentage is lower than desired: difference = current + desired.
