Details

Steps to reproduce:

Using day and week view in calendar.

Actual results:

The time column (00:00, 01:00, … 23:00) appears optically turbulent, since normal numbers are used (different width, good for continuous text), even if the font in use supports "tabular numbers": alternate number glyphs with a unified width, "tnum".

Expected results:

Modern fonts support "tnum" alternates, specifically designed for this case. (For example: https://rsms.me/inter/#features … search for "tnum".) They should be used here.
I'm not a developer, but

-moz-font-feature-settings: "tnum";

may be solve the issue.
