Is it possible to calculate havdalah times based on 8.5 degrees rather than minutes?

Our community (Wellington, New Zealand) uses the 8.5 degrees method for havdalah time which varies noticeably from any fixed minutes after sunset at times of the year. Is it be possible to specify this method as an alternative to minutes after sunset?

Thanks for using Hebcal and thanks for your question!

No, we don't currently support Havdalah by solar degrees below the horizon. This is an excellent idea, and one that we'll consider implementing.
