How to calculate Easter in Metatrader by formula?

[maximo]

I'm doing a project for the community to make a perpetual calendar holiday indicator to advise markets are closing early today and

need to convert an Excel formula that should calculate the day of Easter (Sunday) then -2days for today Friday a trading day.

Would just like the formula to work in Metatrader if possible?

   // excel formula for Easter:   =ROUND(("1/4/"&A1)/7+MOD(19*MOD(A1,19)-7,30)*14%,)*7-6 

   // or:   =FLOOR(DATE(YEAR,5,DAY(MINUTE(YEAR/38)/2+56)),7)-34 

   // where A1=the year

   // source https://www.mrexcel.com/board/threads/how-to-calculate-the-date-of-easter.389703/

   So far..

   int A1=Year();  // may be a double?

   int Easter = MathRound(("1/4/"&A1)/7+MathMod(19*MathMod(A1,19)-7,30)*14%,)*7-6;

   Not sure if the &  tries to mask a quarter of the year or what at this point 🤔 

   Credit will be given to person who solves.

   

  Happy Easter!
