Weather service not working anymore?

Apixu free tier does not provide astronomy data. Moon phase calculation is relatively simple. Here's a formula that gives number of days since new moon cycle:

Code:

local date = os.date('*t')
local y, m, d = date.year, date.month, date.day

if m < 3 then
  y = y - 1
  m = m + 12
end

local a = math.floor(y / 100)
local b = math.floor(a / 4)
local c = 2 - a + b
local e = math.floor(365.25 * (y + 4716))
local f = math.floor(30.6001 * (m + 1))
local jd = c + d + e + f - 1524.5  

local dn = jd - 2451549.5
local nm = dn / 29.53
local dc = (nm % 1) * 29.53

log(dc)
