Bangkok: Today marks the summer solstice, the longest day of the year, as the sun reaches its northernmost point in its orbit. This astronomical event results in the sun rising furthest to the northeast and setting furthest to the northwest. As a result, countries in the Northern Hemisphere, including Thailand, experience extended daylight hours, while those in the Southern Hemisphere face shorter days and longer nights.

According to Thai News Agency, the National Astronomical Research Institute of Thailand states that in Thailand, the sun rises at approximately 5:51 AM and sets at approximately 6:47 PM, providing about 12 hours and 56 minutes of daylight. Although this day offers the longest daylight hours in Thailand, the country's proximity to the equator and its monsoon climate mean that seasons are primarily influenced by weather patterns. The summer solstice typically coincides with the rainy season in Thailand. This day marks the transition to summer in the Northern Hemisphere and the beginning of winter in the Southern Hemisphere.
