- **Keywords:** daylight, sunrise, sunset, sun, astronomy, daylight hours, day length

## Overview

The Daylight Calculator computes precise daylight hours, sunrise, and sunset times for any global location and date. Input latitude, longitude, and a date to receive accurate astronomical data in JSON format.

## Inputs

- **Latitude** (number): Enter latitude (-90 to 90)
- **Longitude** (number): Enter longitude (-180 to 180)
- **Date** (date): Select date

## When to use

- When planning outdoor events or activities that rely on natural light conditions.
- For astronomy or stargazing to determine optimal observation windows based on daylight.
- In agriculture or gardening to schedule tasks like planting or harvesting according to daylight exposure.

## How it works

- Enter the latitude coordinate (-90 to 90) for your location.
- Input the longitude coordinate (-180 to 180) for your location.
- Select the date for which you want to calculate daylight.
- The tool processes the inputs using astronomical algorithms and returns results including sunrise, sunset, and daylight duration in JSON.

## Use cases

- Scheduling photography sessions to capture sunrise or sunset lighting.
- Assessing solar energy potential by analyzing daylight hours for a location.
- Planning outdoor sports or recreation activities based on available daylight.

## Frequently asked questions

### How accurate are the daylight calculations?

Calculations are based on standard astronomical formulas and are highly accurate for most practical purposes.

### Can I use this tool for historical or future dates?

Yes, you can input any valid date, past or future, within the tool's supported range.

### What if I don't know my exact coordinates?

Use online maps or geolocation tools to find the latitude and longitude for your specific location.

### Are the output times adjusted for my time zone?

Output times are provided in UTC; you may need to convert them to your local time zone manually.

### Can I calculate daylight for multiple dates at once?

No, the tool processes one date per calculation; run it separately for each date you need.
