从2023年4月到2024年3月，一年的日落沿着西方的地平线堆叠在这些全景中。这个精心策划的序列是由在指定月份的21日附近从俯瞰埃及开罗的同一地点拍摄的图像组成的。但在地球上的任何地方，每年的最北（图右）和最南的落日边界标志着冬至日。夏至一词来自拉丁语，意为“太阳”和“站立不动”。在冬至日，太阳每日在天空中运行的路径似乎会暂停，并在一年一度的天体之旅中逆转方向。当然，太阳在今天的日期是静止的。2024年12月21日09:21 UTC是太阳最南端赤纬的时刻，也是天文上北方冬天和南方夏天的开始。

A year in sunsets, from April 2023 to March 2024, track along the western horizon in these stacked panoramic views. The well-planned sequence is constructed of images recorded near the 21st day of the indicated month from the same location overlooking Cairo, Egypt. But for any location on planet Earth the yearly extreme northern (picture right) and southern limits of the setting Sun mark the solstice days. The word solstice is from Latin for "Sun" and "stand still". On the solstice date the seasonal drift of the Sun's daily path through the sky appears to pause and reverse direction in its annual celestial journey. Of course the Sun reaches a stand still on today's date. The 21 December 2024 solstice at 09:21 UTC is the moment of the Sun's southernmost declination, the start of astronomical winter in the north and summer in the south.
