Most likely the reason is, what is described in section genVisibleTimespans() <https://github.com/roe-dl/weewx-skyfield-almanac?tab=readme-ov-file#genvisibletimespans> of the documentation. There, a special generator function is described that returns timespans of visibility. It reads:
"If you wonder why you could not use a loop over the days as the tags $week.days, $month.days, and $year.days provide and then calculate rising and setting time, here is the answer: You can do so with PyEphem, but unfortunately this approach is 125 times slower with Skyfield. Therefore a specialized method is required." -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
