Windows 10 Calendar Flyout Update: The Return of Clock Seconds
In a nostalgic twist, Microsoft is reintroducing the ‘seconds’ feature to the Calendar flyout on Windows 10. This change comes after user outrage over its removal, occurring as we near the operating system’s end-of-support date set for October 14, 2025.
A Quick Recap of Changes
The saga began in January 2025, when I first highlighted the updated Calendar flyout UI. While the interface aimed to enhance user experience with events, it controversially omitted seconds from the taskbar clock, much to the dismay of many users.
Over the months, the absence of seconds in the clock went unnoticed by Microsoft, despite being a topic of discussion among users. Even as seconds were retained in Windows 11, many Windows 10 users felt overlooked.
Official Acknowledgment from Microsoft
Finally, after much feedback from users, Microsoft has noted that the seconds feature, previously removed in an unnamed update, is making a comeback. This confirmation was included in the release notes for Windows 10 Build 19045.5912, stating: “Brings back the clock view that displays seconds onto the calendar that was once removed.”

Interestingly, user experiences varied widely based on update rollouts; some users had lost the seconds display as early as January, while others retained it until this update. In fact, I conducted an experiment with ten virtual machines, where two still showed seconds. It’s peculiar considering they are identical machines!
Exploring the Enhanced Calendar UX
Microsoft’s commitment to enhancing the Calendar experience is evident in its new “Rich” UX. As I tested this update, I found that simply hovering over dates below the clock provides a preview of the day’s events. If you click on a specific event, Windows opens Edge, performing a Bing search related to that event. While this may seem like an implicit promotion for Bing, it aligns with practices seen across other platforms.

If you prefer a more streamlined Calendar flyout display, you can take advantage of the three-dot menu to hide the agenda setup, allowing for a cleaner interface.
Rollout Timeline and Future Updates
The much-anticipated Calendar flyout update including the seconds feature will begin rolling out in late May 2025 and will be widely available with the June 2025 Patch Tuesday on June 10, 2025.
What are your thoughts on the revamped Calendar UI for Windows 10? Personally, I find the improvements a significant enhancement!
