Ok - don't laugh

My coding skills are pitiful so I asked my resident Ai to write a bash 
script to call a webcam script (I did write this one) only between 
sunrise and sunset. it produced this and it works! My question is - how 
can I amend the script so it starts 30 minutes BEFORE sunrise and stops 
30  Minutes after?

#!/bin/bash

# Set your latitude and longitude
LATITUDE="mine"
LONGITUDE="mine"

# Fetch sunrise and sunset times in UTC
SUN_TIMES=$(curl -s 
"https://api.sunrise-sunset.org/json?lat=$LATITUDE&lng=$LONGITUDE&formatted=0")
SUNRISE=$(echo $SUN_TIMES | jq -r '.results.sunrise')
SUNSET=$(echo $SUN_TIMES | jq -r '.results.sunset')

# Convert sunrise and sunset times to seconds since epoch
SUNRISE_EPOCH=$(date -d "$SUNRISE" +%s)
SUNSET_EPOCH=$(date -d "$SUNSET" +%s)
CURRENT_EPOCH=$(date +%s)

# Check if the current time is between sunrise and sunset
if [ $CURRENT_EPOCH -ge $SUNRISE_EPOCH ] && [ $CURRENT_EPOCH -le 
$SUNSET_EPOCH ]; then
     echo "It's between sunrise and sunset. Running the other script..."
     # Call the other script
     ./webcam.sh  # Replace with the path to your script
else
     echo "It's not between sunrise and sunset."
