Dark hours calculator

[old_eyes]

Some time in the past I found a useful tool/site that gave me a visaulisation of dark hours for the UK throughout the year.

Now I can't remember where I got it.

There are plenty of tools that give me the information for today, and ClearOutside gives me a week look ahead. These are very useful, but I like to be thinking about what is above my imaging horizon when we have astro-dark  in the future. It helps me plan the targets I would chose in the unlikely event that I have clear skies.

Does anyone recognise this, or can point me at a tool that does something similar?

Thanks. That will do nicely.

There's also the APT DC app which tells you how much imaging time you have for any given night.

Nice. Looking at that I have 11 days left until I get astronomical darkness back in my location.  Even better as it co-insides with me going to a darker sky location (bortle 8 to bortle 4) for a week
