Not to be "that guy", but claiming that 4:15am in California (11:15 UTC) is daylight is really stretching it, at least going by this morning. Also sunrise here is ~5:50 AM. Even for a 7am meeting I typically need lights on in my office until partway through. The room has both eastern and southern exposure in the south-east corner (my desk is literally by the windows).

The article points out that it will be astronomical twilight, which most people aren't able to notice visually:

> This is especially true for those who reside on the outermost edge of the twilight zones, within the darkest twilight phase called astronomical twilight. Here, the Sun is 12-18 degrees below the horizon. At that angle, the indirect sunlight becomes so thin that it is usually indiscernible to the naked eye.

The article suggests 83% to 90% (not 99%) of people will find it to be light out (daylight or civil twilight) ... not including Californians.

In the interest of cranking up the pedant-o-matic machine:

(1) If astronomical twilight and other indirect sunlight counts, then moonlight counts doubly so!

(2) If indirect and thus spatially separated sunlight counts, then temporally removed sunlight, in the form of airglow, should count as well!

(3) Starlink will also become a factor or heck, any of the planets visable in the sky as well.

Given that, the caviet of direct and indirect sunlight is a huge factor not quantified.

Yes, being "in sunlight" and seeing reflected light from the sun are two different things.

Sunrise means that the sun is fully above the horizon. Dusk is when the sun light is starting to appear but the sun is still below the horizon. So yea I think the original 99% is experiencing daylight is from from accurate but almost everyone will be experiencing sunlight… technically.
