Mastering Blue Hour Timing on Your Apple Watch

Blue hour—the period of twilight when the sun is between 4° and 6° below the horizon—offers photographers and outdoor enthusiasts a unique, ethereal light. This phase occurs twice daily: in the morning, approximately 20–40 minutes before sunrise, and in the evening, about 20–40 minutes after sunset. (rawkiln.com)
