How to calculate this in AMS

[Friethoe]

Hi,

In Excel I have a formula to calculate Easter and I need this formula to do in a AMS project, but I can't figure out how to do this.

In Excel the formula would be like this:
Cell A1=1-4-2015
Cell A2=FIXED((A1)/7+MOD(MOD(YEAR(A1);19)*19-7;30)*14%;0)*7-6

That works like a charm, but to port it to AMS , can you help me?!

Thanks,
Eric

Hi,

I found it and if you need it too some day, here it is:


function Easter(year)
local leap_year
if year % 4 == 0 then
if year % 100 == 0 then
if year % 400 == 0 then
leap_year = true
else
leap_year = false
end
else
leap_year = true
end
else
leap_year = false
end
local a = year % 19
local b = math.floor(year / 100)
local c = year % 100
local d = math.floor(b / 4)
local e = b % 4
local f = math.floor((b + 8) / 25)
local g = math.floor((b - f + 1) / 3)
local h = (19 * a + b - d - g + 15) % 30
local i = math.floor(c / 4)
local k = c % 4
local L = (32 + 2 * e + 2 * i - h - k) %7
local m = math.floor((a + 11 * h + 22 * L) / 451)
local month = math.floor((h + L - 7 * m + 114) / 31)
local day = (h + L - 7 * m + 114) % 31 + 1
if month == 2 then --adjust dates in February
day = leap_year and day - 2 or day - 3
end
return day, month
end
