37074	"""Today"" in admin datetime widget differs from ""today"" in calendar picker display"	Jacob Walls		"The calendar widget for date fields in the admin has a discrepancy in how ""today"" is calculated.

The widget input treats ""today"" as in server time.

But the highlighting in bold of ""today's"" entry on the calendar squares (`class = ""today""`) is calculated in local time. (After #36459 this will also affect an aria-label on that square.)

This means that for a TIME_ZONE of UTC+12 (`TIME_ZONE = ""Pacific/Nauru""`) and a local time of something else (for me, `America/NewYork`), the ""Today"" button produces the date in Nauru, but the previous date is highlighted with `class=""today""`.

The proposal for #35951 passes the server timezone to the frontend. Once that is in place, we can use it to remove this discrepancy by making ""today"" always calculated the same."	Bug	new	contrib.admin	dev	Normal				Unreviewed	0	0	0	0	0	1
