Solar Day Elevation Sizer is a verified time, date & age (dob) calculation tool on Calcify. Calculate solar declination angle δ, solar noon peak elevation angle, and daylight hours for any latitude and day of year. All calculations execute locally in your browser with multi-currency support, visual breakdowns, and white-label client exports.
Daylight Duration: 13.82 Hours | Solar Declination δ = 23.45°
Declination δ = 23.45° × sin[ 360/365 × (284 + N) ]; Noon_Elevation = 90° - |Latitude - δ|
Example Inputs: Observer Latitude (°N positive / °S negative): 28.61 ° · Day of Year N (1 = Jan 1, 172 = Jun 21, 355 = Dec 21): 172
Example Output: Solar Noon Peak Sun Elevation: 84.84° (Daylight Duration: 13.82 Hours | Solar Declination δ = 23.45°)
The Solar Day Elevation Sizer on Calcify applies the verified mathematical formula: Declination δ = 23.45° × sin[ 360/365 × (284 + N) ]; Noon_Elevation = 90° - |Latitude - δ|. Every input is validated in real time with multi-currency formatting to ensure zero rounding or division errors.
