Maybe you can use a part of my script. I use the api for getting the total minutes of daylight. But when you have the time for Sunrise or Sunset you can calculate the minutes till 0:00.
Solar panels prognose with daylight minutes
This is the api call:
url = (‘https://api.sunrise-sunset.org/json?lat='+latitude +’&lng=‘+longitude +’&date=’ + currentYear + ‘-’ + currentMonth + ‘-’ +count +‘&formatted=0’);
Just take a look at the website sunrise sunset
