Ocampan calendar

• Length of Ocampan year derived from Kes age references
  • Exactly two years old in "Twisted" (between SD 48921 and SD 48975)
  • 3 years and 2 months in Before and After (SD 50812)
  • Thus 670-690 Earth days = ~1 year 2 months Ocampan time, implying one Ocampan year = between 1.48 and 1.62 human years
    • Assuming average of 1.55 human years (or 566 days) per Ocampan year
  • Derivation requires ignoring "not even a year old" comment from Doctor in Before and After flashback describing her as of "Caretaker", but incompatible with Twisted even if assuming Earth time anyway
