Clock Format & Graph: This clock divides your day and night into four solar periods based on the sun's actual position:
SR (Sun Rising): Time from Sunrise to Solar Noon. Counts up.
SS (Sun Setting): Time from Solar Noon to Sunset. Counts down.
NR (Night Rising): Time from Sunset to Nadir (solar midnight). Counts up.
NS (Night Setting): Time from Nadir to the next Sunrise. Counts down.
The graph visually represents this cycle as a sine wave. The upper curve is daytime, the lower curve is nighttime. You can set alarms by clicking on the graph. The red dot shows the current solar time.
Circadian Health: Your body's internal clock (circadian rhythm) is naturally tuned to the sun's cycle. Aligning your activities, especially sleep and light exposure, with this natural rhythm can improve sleep quality, energy levels, and overall well-being. This clock helps you visualize and connect with these natural cycles, which can be obscured by artificial lighting and fixed standard time zones.
Benefits Over Standard Time: Standard time uses fixed zones and often doesn't reflect the true local solar day. Sun Based Time is dynamic and tied to your specific location's sunrise and sunset. This provides a more natural and personalized way to perceive and organize your day, potentially encouraging habits more in sync with daylight and darkness.
