Follow the rhythm of daylight
Choose a North American city to preview today’s sunrise, sunset, and daylight length.
A clearer way to see sunlight.
Explore daylight rhythm with a city-based annual view.
Sunrise, sunset, and daylight duration depend on latitude, longitude, date, and time zone. MixCalendar starts with a city profile and can personalize the view with a location you approve.
Use the chart to compare seasonal daylight patterns rather than precision twilight conditions. Buildings, terrain, atmospheric refraction, and elevation are not fully modeled.
Read our data and calculation methods for coverage and accuracy limits. If a date or result looks wrong, report a calendar error.
Good to know
Does MixCalendar use my location automatically?
No. Location access requires your browser permission, and a supported city remains the fallback.
Why do official weather services differ slightly?
Professional services may use more precise coordinates, elevation, atmosphere, and horizon models.
