Month
From Tardis Wiki, the free Doctor Who reference
A month was a unit of time measurement. According to the Fourth Doctor — who was almost certainly speaking of its duration on Earth — a month lasted 2,678,400 seconds. (TV: The Brain of Morbius)
Months had individual names. Known months — not all of which were Earth months, and so not all of which could possibly equal 2,678,400 seconds — included:
- January
- February
- March
- April
- May
- June
- July
- August
- September
- October
- November
- December
- Clavadoe
- Hoob
- Pandoff
- Akhit
- Paztenmber
- Novrimber
- Fennestry
Behind the scenes
Though he doesn't specify in the script of Morbius, the Doctor's sums reflect a 31-day month.
