Thanks for the summary. Irksome/Curious that the page throws up such a blanket go-away screen when I am using an iPad, which from my perspective is basically the same as a small laptop (only in the browser ofc).
For me on desktop there's no info other than "Henge Finder requires a desktop or laptop computer" (Chrome/Edge/Firefox on Windows, not exactly uncommon!).
The following in the browser console will enable it:
document.querySelector('.mobile-block').remove(); document.querySelector('.container').style = ''
> Finds when the sun aligns with your street for a perfect sunset view (like Manhattanhenge).
> * Enter an address to check for alignment with the sunset (or more specifically, alignment a little before sunset, the last moment the sun is at 50˚)
> * Shows street bearing and sun alignment information
> * Displays coordinates and next henge date (if there is one)
