Ordinal Dates for today, tomorrow, and yesterday... #zsh #today #tomorrow #yesterday #ordinal #date

Likely pretty ghastly, but I wanted Ordinal Dates for today, tomorrow, and yesterday...

#!/bin/zsh
# set -x

alias date=/usr/local/opt/coreutils/bin/gdate

today () {
    echo $(date --date='today' +%e)
}

tomorrow () {
    d=$(date --date='today' +%a)
    if [[ $d = "Fri" ]]; then
        echo $(date --date='next Monday' +%e)
    elif [[ $d = "Sat" ]]; then
        echo $(date --date='next Monday' +%e)
    selse
        echo $(date --date='tomorrow' +%e)
    fi
}

yesterday () {
    d=$(date --date='today' +%a)
    if [[ $d = "Mon" ]]; then
        echo $(date --date='last Friday' +%e)
    else
        echo $(date --date='1 days ago' +%e)
    fi
}

ord () { 
    # d=$(date +%e)
    d=$1
    case $1 in
        1?) d=${d}th ;;
        *1) d=${d}st ;;
        *2) d=${d}nd ;;
        *3) d=${d}rd ;;
        *)  d=${d}th ;;
    esac
    echo $d
}

#echo "Yesterday"
yd=$(yesterday)
o=$(ord $yd)
p=$(date "+%b $o, %Y")
echo "Yesterday : [[$p]]"

#echo "Today"
# td=$(today)
# o=$(ord $td)
