Solar Noon Calculator日中与正午计算器
Solar noon is not 12:00. Find the true peak of the day for your longitude and date.日中午刻并不是 12:00。根据你的经度与日期，找到一天中太阳真正的最高点。
Solar noon is late in the west of a timezone and early in the east, plus the Earth's elliptical orbit shifts it by up to ±16 minutes across the year. In western China (UTC+8), solar noon can be after 14:00.时区西部日中午刻偏晚、东部偏早；加上地球椭圆轨道，一年中还会在 ±16 分钟之间摆动。在中国西部（UTC+8），日中午刻甚至可能晚于 14:00。

- Solar noon is the exact moment the sun crosses your meridian — the day's highest, most symmetric light.日中午刻是太阳精确经过你经线的时刻——一天中最高、最对称的光线。
- Use it to plan vertical-light shots, to calibrate other apps, or to predict when shadows will be shortest.用它规划顶光拍摄、校准其他应用，或预测影子最短的时刻。
