Set a schedule so Windows switches to dark mode at sunset and back to light mode at sunrise automatically.
Pair a dark desktop wallpaper with dark mode and a light wallpaper with light mode for a cohesive look throughout the day.

Windows Auto Night Mode is a lightweight utility for Windows 10 and Windows 11 that automatically switches the operating system between its dark and light themes based on a schedule you define. The description captures the purpose precisely: it handles the theme switch so you do not have to do it manually each morning and evening. Windows 10 and 11 include a dark mode for the system interface, app windows, and some desktop elements. By default, switching between dark and light requires going into Settings and changing the option by hand. This tool removes that step by detecting the time and triggering the switch automatically. The topic tags associated with this repository include dark-theme, darkmode, light-theme, lightweight, theme-switch, wallpaper-changer, and windows. The wallpaper-changer tag suggests the tool can also swap the desktop wallpaper when the theme changes, so the overall desktop shifts from a light daytime look to a darker nighttime one as a unit. The application is written in C#, which is a programming language commonly used for Windows desktop software. The lightweight topic tag indicates it is built to run quietly in the background without using significant system resources. With over 9,400 stars on GitHub, the tool has built a large user base among Windows users who prefer dark mode in the evening. It fills a gap that Windows does not natively cover: a time-based schedule for automatic theme switching. Users set their preferred switch times once, and the app handles the rest.
