Wednesday is the first day of the week.
Well come on . You're a funny guy , I played along with your zombie game . Let's hear why ?
The Jewish day of rest is Saturday. If anyone knows when the day of rest is, it's them.
Hence, Sunday is the first day of the week.
God created the world in 6 days according to Genesis, and allotted the last as a day of rest. Monday is the beginning of the week.
That day of rest was Saturday therefore the first was Sunday
