Longest Day (Summer Solstice) – June 21, 2023

The Longest Day (Summer Solstice) is observed on either June 20, 21, or 22, but this year, it falls on June 21. The timing shifts because it depends on when the Sun reaches its northernmost point from the celestial equator.

It signals the start of astronomical summer. As a result, the days get shorter as summer progresses, first gradually but then at increasingly larger daily intervals as the September equinox approaches and ushers in the beginning of fall. Because the Sun travels across the sky in its most elongated path during the summer solstice, that day has the most daylight hours.

History of Longest Day (Summer Solstice)

The day of the summer solstice, which occurs when the Sun is at its farthest distant point from the equator, is also the day that is considered to be the longest of the year. Since the Neolithic era, this day has been observed as the summer solstice, also known as the summer’s midpoint.
In the Neolithic cultures of Northern and Central Europe, the dates of the crop cycles were associated with the summer solstice. People in Celtic, Slavic, and Germanic cultures traditionally celebrated it by lighting bonfires to bolster the Sun’s vigor for the duration of the crop season and ensure a healthy harvest.

Numerous Neolithic stone circles appear to have been constructed around the Sun’s movement at solstices. However, because there are no written accounts from this time period, determining the exact purpose of these rock edifices is difficult. On the other hand, the stones appear to be carefully positioned to align with the Sun’s movements, framing solar motion on the summer and winter solstices.

Stones at specific solstice axes were even hammerstones to frame the sunrise for those standing in the center of the circle. This suggests that the alignment of the stones with the Sun’s motions was intentional. The summer solstice was regarded as a significant cultural event in many ancient communities, and it is still regarded as such by some modern groups.
