Yes but you said that "sunrise and sunset are solar reckoning" and I wasn't taking issue with the topic of lunar/solar calendars because calendars don't count off or delineate the hours in a day.

Every calendar that I'm aware of considers "days" as an abstract unit which consists of one planetary rotation, without nuances of activity or visibility of external bodies, right? True?

What I meant was that for an observant Muslim, the month start and month end date of Ramadan is set by the moon, but also each day has a very slight different sunrise time and Iftar time (sunset, when you can eat and drink again) which is dependent on the sun's position.

You are right that the human perceived calendar date is something we invented rather arbitrarily. Of course, the longest day of the year was occurring on June 20th before humans invented agriculture or cities. That we call it "June" and "20" is a cultural artifact.

> dependent on the sun's position

Check your geocentrism

The Sun’s relative, apparent position.

Sunrise and sunset are wholly dependent on the observer’s position because “night” is a cultural construct referring to being within the Earth’s shadow rather than a dragon devouring the Sun, yes?
