Date range header blinks repeatedly when navigating calendar views

[Maqsood-Ansari]

Issue Summary

I noticed a UI bug in the date-range header on the scheduling calendar.
When switching from weekly view to column view on the top right corner, the displayed date range keeps blinking between two different formats.

What happens:

The date header alternates rapidly between:
“Nov 24 – Dec 5, 2025”
“Nov 24 – 29, 2025”

This blinking continues repeatedly.

Expected behavior:
The date range should remain stable and correctly represent the selected calendar range without flickering.

Steps to Reproduce

1. Open https://cal.com/anovoszath/60m?layout=column_view
2. Navigate to a date range around late November 2025
3. from "switch to weekly view" to "switch to column view"
4. Observe the header at the top of the calendar
5. Notice the date text flickers between two values

Actual Results

The date-range text at the top of the calendar keeps blinking repeatedly between two different ranges:
“Nov 24 – Dec 5, 2025”
“Nov 24 – 29, 2025”
This flickering continues each time the calendar loads or when switching between views.
It looks like two separate date calculations/render cycles are competing, causing the UI to alternate.

Expected Results

The date-range header should show a single stable and accurate range for the currently selected calendar view.
The text should not flicker, change, or re-render repeatedly.

Evidence
