Mean Solar time

Why not include an option to show the mean solar time instead of legal time?

Show time difference between local and UTC

To me it is unclear wether the times are local or UTC. Anyway, Presenting the difference between UTC and local time would be a great option for my daily work (aviation).

Slider moving in realtime

It would be great to see the slider move in relation to hours/minutes/seconds elapsing. In other words, the page currently has to refreshed or the "Now" button has to be clicked on in order to see current time. I don't know how difficult it would...

Choice of twilight type(s) (civil/naut/astro) shown in the slider

The light blue areas in the slider currently seems to show civil twilight. Since I am more interested in the nautical than the civil twilight, I would like either all three twilights in somewhat different colors, or the ability to select which...

Thank you for an outstanding tool. Great stuff!

We are designing a home and we have the freedom to rotate the house on a large block. This tool took all the guess work out positioning for the best winter/summer sun and it is far easier to use than anything else we found. Well done and thanks...

Country time change dropdown

If I'm researching the sun angle and times in different countries, the time indicated always appears to be the correct time where my IP originated. Could you possibly include a time clock dropdown to alternate between the time where the viewer...

Mountains!

It has already been asked before, but here it is again, it is the most beneficial improvement one could imagine on this (otherwise great) app: account for mountains. The current figures are largely invalid for large parts of the habited world,...

I would like to view the details with local time of the place in reference too.

I would like to view the details like times of Sunrise, Sunset etc. with reference to local time of the place for which I am viewing the Suncalc. as well as in relation to my time, which I can see now. May be as an option to view in either way.

add local hourly temperature

Please add local hourly temperature, based on the nearest weather station. This data could produce a solar window that can depict the heat raising on a specific zone. Perfect for architect and farmer. Perhaps you can work together with:...

When clicking "more detailed", it would be nice if the astronomical, nautical and civil twilights were also shown on the timeline.

Azimuth (bearing) for sunrise and sunset.

Azimuth and altitude would be great for any time of day, but if that is too complex just azimuth (bearing) of sunrise and sunset would be very useful. Great app. Serves a need for me, having used a spreadsheet for numerical calculations for...

Ultimately be able to create and also to import object(S) and place them in map and see the shadows

And ultimately, at some point of development, also be able to rotate the map/area, including the objects, to view from different angles, and view from different heights too, in 3D. I.e. to be able to move the point of view around, while looking at...
