## calculations
# all of the calculations are done using unix timestamps from date(1)

# mac uses bsd's date(1)
# whenever we set a date, make sure to add -j so it doesn't change the clock

# we use `date -j %m%d0000 +%s` to get the start timestamp, %Y is implied
# then we use `date -jr $start -v +1y/+1m/+1d +%s` to get the ending timestamp
# then we calculate the percentage with (now - start) / (end - start)

now=$(date +%s)

Y=$(date +%Y)
Y_start=$(date -j 01010000 +%s)
Y_end=$(date -jr "$Y_start" -v +1y +%s)
Y_progress=$(
    echo "($now - $Y_start) * 100 / ($Y_end - $Y_start)" | bc -l
)

m=$(date +%m)
m_start=$(date -j "$(date +%m)"010000 +%s)
m_end=$(date -jr "$m_start" -v +1m +%s)
m_progress=$(
    echo "($now - $m_start) * 100 / ($m_end - $m_start)" | bc -l
)

# If time right now is working_start is less than the starting time but
# midnight, set to "SLP" without %

d=$(date +%d)
d_start=$(date -j $working_start +%s) # starttime of today

# set the end time
d_today=$(date -j "$(date +%m%d)"0000 +%s)
if [ $working_end -eq 0000 ]
then
    d_end=$(date -jr "$d_today" -v +1d +%s) # beginning of next day
else
    d_end=$(date -j "$(date +%m%d)$working_end" +%s) # set to working_end time of today

d_progress=$(
    echo "($now - $d_start) * 100 / ($d_end - $d_start)" | bc -l

## output prep
# padding to align progress bar and text
# Y-m-d = 10 + 2 spaces + 2 digits + percent sign = 15
# progress bar width - 15 = padding
padding=$(printf %$((width-6))s "")

# round function
round() { printf %.0f "$1"; }

# progress bar display function

    # repeat the characters using printf
