Sunrise/sunset time discrepancy

I like having sunrise/sunset as a datafield on my default watchface and also as a widget. Strangely, they are sometimes different, usually by a minute. Any idea why?

Very few IQ elements in the store are written by Garmin itself. Usually it's people who do this as a hobby. You too could develop IQ Apps if you learned to do so. Garmin…

I often experience the same. But considering the sun doesn't literally set during one precise minute, but rather it's a slow transition that takes 10+ minutes, I really don't think a 1 minute discrepancy…

Anything downloaded from the CIQ store is not a standard Garmin watch face. Can you link to which one you are using?

IQ watchfaces are developed by private devs, usualy. Everyone uses another algorithm. Try to use a built in garmin watchface, and the original garmin widget.

but i think one minute is ok. Please remind that the f6x have a 7 second tine lag.

I often experience the same. But considering the sun doesn't literally set during one precise minute, but rather it's a slow transition that takes 10+ minutes, I really don't think a 1 minute discrepancy is really going to matter to anyone. It's probably just caused by a rounding error. It might trigger people's OCD, but that's about it. It's like accidentally leaving a turkey in the oven for 3 hours 31 minutes instead of 3 hours 30 minutes, it's probably not going to burn the turkey, but my perfectionist spouse will get upset anyways.

and the windget is also from garmin? Or from other developer from IQ Store ?

Yes, Garmin widget

Ok, then it should be look like this:

so, mine is correct. Both 19:01 sunset,

if your widget looks different, its not the preinstalled garmin widget. Then you downloaded it at the store, and is perhaps not from garmin.contact the developer. But +/- 5 minutes are normal differences. Belongs to the code algorithm calculating the sun event times.

So let’s say sunrise is 6:01 and sunset is 5:07. Both the widget and watch face (just one time) reflects this, check. So you do things throughout your day and it’s now 5:08. If you looked at your widget (for the sunrise time) and looked at your data field, they won’t match. The data field will reflect “tomorrows” sunrise, where the widget is reflecting today’s. If you looked at the next day on the widget, it would reflect the minute difference.

This only applies to stock Garmin watch faces.

Also just in case people aren't aware, sunrise/sunset events can change by a minute or two just by driving a very short distance. Depending on where you are on the planet, driving 13 miles west will reduce the sunrise/set times by a minute, and driving east 13 miles will increase it by a minute. Seriously, just 10-15 miles is all it takes to affect what time the sun rises or sets. So it wouldn't be unsual for you to be "going about your day" and see the sun event times going up or down by a minute or two throughout your day.
