Daylight Duration日照时长
From sunrise to sunset — total daylight minutes for any date, and how the year changes your shooting window.从日出到日落——任意日期的日照总时长，以及一年中拍摄窗口的变化。
- Set your location and the date you are scouting.设置你的位置与踩点日期。
- Read your total daylight, then compare it with the solstices to understand where you are in the year.查看你的日照总时长，再与二至日对比，了解一年中你处于什么位置。
- Use the comparison to decide how early to arrive — in spring, golden hour slides later every day; in autumn, earlier.用对比结果决定提前多久到达——春季黄金时刻每天都推迟，秋季则逐日提前。
Daylight changes fastest around the equinoxes (up to ~3 minutes per day at mid-latitudes) and barely at all around the solstices. That is why summer sunrise times feel "frozen" for weeks.日照在春秋分前后变化最快（中纬度每天可达约 3 分钟），在二至日前后几乎不变。这就是为什么夏季日出时间会“冻结”数周。
