The Summer Solstice in the northern hemisphere typically occurs around June 21st and is characterized by the longest daylight hours of the year.
Looking at the daylight hours for each day:
- Day 1: 12 hours 12 minutes
- Day 2: 15 hours 13 minutes
- Day 3: 12 hours 7 minutes
- Day 4: 9 hours 8 minutes
Day 2 has the longest daylight hours at 15 hours and 13 minutes, making it the most likely candidate for the Summer Solstice.
So, the correct response is Day 2.
