Planning by daylight
Sunrise and sunset for your location set the shape of every day, all year round. Your plan stretches in summer and tightens in winter.
Good afternoon
Plan your day around the light.
Dayarc places your deep work in your brightest hours and lets rest arrive as the light fades, so your schedule finally follows your energy.

Why Dayarc
Your calendar knows the time. Not the light.
Deep work lands at 3 PM
Because that is where the calendar had a gap, not where your focus peaks.
Rest gets squeezed out
The evening fills up and the slow, restorative hours never get planned.
Every planner ignores the sun
Light shapes alertness, yet your schedule treats 7 AM and 7 PM as the same.
How it works
One day, four kinds of light.
Dayarc follows the sun where you are and gives each part of the day the work it suits.
Dawn · First light
Ease in
Light admin, planning and movement while your energy climbs.
Day · Brightest hours
Deep work
Your hardest, most focused task gets the peak of the day.
Dusk · Light fading
Wrap and connect
Meetings, messages and loose ends as focus softens.
Night · After dark
Rest
Nothing scheduled that asks for focus. Wind down on purpose.

FAQ
Good questions.
Is Dayarc available yet?
Not yet. Dayarc is in early access, and joining the waitlist is the way to get an invite.
What does it cost?
It is free during early access. We will tell you well ahead of time about anything that changes.
How does it know when it is light?
It uses sunrise and sunset for your location and time zone, so it works the same in Oslo, Lagos or Lima.
Do I need to share my exact location?
No. A city or time zone is enough to work out your daylight.
Will it work with my calendar?
Calendar sync is planned, so your meetings can sit alongside your light-based plan. Join the waitlist and we will tell you when it is ready.
