I experience a flow state around that time as well. Mostly because everyone leaves the office. 0630-0730 and 1630-1730 have become my golden hours. Which is weird because body doubling is often an effective tool for me. My true “0430” like the parent comment is really at 2000, but I force myself into a normal sleep schedule and fail often.
Yeah. My body/brain's natural "mental flow" time is really early mornings.
In reality, I generally have too much external distraction around me in the morning to capitalize on this.
So my actual productive hours are basically like, "whenever I am reasonably sure that everybody else will leave me the fuck alone for the next few hours." Which often means, "the end of the work day when everybody is signing off for the day."
Does the time change for you with season and light exposure? I sometimes experience this sort of thing too, where I will have a consistent window of productivity at an unusual time, but it never lasts for a more than a few months.
