If you're wondering what Suncurves does: We've developed a method to compute accurate sunrise and sunset times for every day of the year. Most other sites don't take the terrain into account. Our sunrise is when the sun rises from behind mountains or hills, not when it goes up over an imaginary flat horizon. We have analyzed 43471 sites around the world and have 16301 registered users.

I was excited to find your service. I am a wedding photographer and had a client asking what would be the best time for her wedding ceremony, in relation to the photographs we'd be doing after the ceremony. She wanted to be sure we had the best light possible for her bride and groom photos. The ceremony will take place just below a mountain top, where the sun can go "down" long before the actual sunset time. Your service was very helpful in determining the best time for my client's ceremony and photos, which is so important for photographers!

I just found your tool today and I am not only promoting it to get free credits, but because it's friggin' awesome! This is EXACTLY what I have been looking for as an outdoor photographer. I am travelling the world and sometimes I can't do location scouting because I just see it once I'm there. And, you saved me an hour of extra sleep next week because I know now the sun won't be out before 9am :)
Cheers from Switzerland, keep up the great work!

I am using SunCurves to assess the amount of sunlight a parcel of potential agricultural land has. The land has a slight slope and we are unsure if it will receive enough sunlight between April and August to grow crops.

I used Suncurves to create a schedule for myself in 2015. My goal is to wake up "with the sun" each day to get my body’s circadian rhythm synchronized with daylight-based zeitgebers help me get better sleep. Suncurves tells me when the sun will get up tomorrow. So I set myself a bedtime alarm for visible sunrise minus 9 hours to ensure I am getting a solid 8 hours of sleep each night. Suncurves is helping me achieve my health goals!

I'm an amateur astronomer, I am trying to find a very accurate terrain profile for my city, useful to input that in an astronomy software and then be able to calculate the times at which the principal stars below the horizon will rise and set.
