Try a Python approach through bash.

Code:

#!/bin/bash
# epoch.sh
# Usage: ./epoch.sh YYYYMMDD
EPOCH=$1
if [ "$EPOCH" == "" ]
then
	exit 1
fi
echo '#epoch.py
import time
mydate='\"$EPOCH\"'
epoch=int(time.mktime(time.strptime(mydate, "%Y%m%d")))
print(time.strftime("%A", time.localtime(epoch)))
exit()' > "$HOME"/epoch.py
DAY=$( python "$HOME"/epoch.py )
echo "$DAY"

Results OSX 10.13.3, default bash terminal calling Python 2.7.x.

Code:

Tuesday
AMIGA:amiga~/Desktop/Code/Shell> ./epoch.sh 20180328
Wednesday
AMIGA:amiga~/Desktop/Code/Shell> _

Note: There is very linited error checking so beware!
EDIT:
This is Python 2.7.10 but I think it works on Python 3.5.2 also.
(I have bent the rules on the Python print statement in 2.7.x AND print() function in 3.5.x...)
