White calendar widget in dark theme

The setting you're looking for is in System Settings > Appearance > Icon & widget style. If set to Default, you'll get white backgrounds on calendar widgets, black backgrounds on stocks widgets, orange backgrounds on tips widgets, etc. Set it to Dark if you want them all dark. Note that this affects the Dock icons, as well.

Great news — the white widget issue is fixed in macOS Tahoe 26.1

If you were seeing bright white widgets while using Dark Mode on macOS 26, that’s now fully resolved in the latest update, macOS Tahoe 26.1. The fix isn’t limited to the Calendar widget — all system and third-party widgets now correctly follow your system appearance. No extra steps or workarounds needed — everything just looks right again.

That is the expected behavior. The default background for the Calendar widgets is white. It's black for the Stocks widgets, gray for the Batteries widgets, orange for the Tips widgets, etc., and setting it to Default will give you those background colors.

What he means is that before Tahoe, when you had Dark mode enabled, both the calendar and reminder widgets were dark, with Tahoe the issue is, that you need to change now the icons to Dark, which unfortunately also changes all other icons as well. I do not like the dark icons but would like to have the widgets dark as it was before.

I've certainly tried. I do not see any way to alter the default background for the widgets but keep their color display. Using the clear or tinted options allows a dark background but with a monochrome foreground.

Moreover it becomes transparent when finder is opened or when im in another app and then switching back to the desktop it displays transparent for a sec and then switches back to white... it's so bad.

It's definitely a bug, hopefully will be fixed later.

Which Calendar Widget?

Sorry. I don't have an answer for you. Mine are what should be expected.

Didn't you post in the Tahoe community previously about this issue?

So, I can't offer any advise I just wanted to say your not alone!, I came looking for solutions and found this thread too, hope to see a fix to separate widgets and icons with this!

Same here.

When changed icon to dark or tinted, the calendar widgets change to a dark theme,

but when revert icon theme to default, the widgets get white.
