Use xtickformat | ytickformat | ztickformat which sets the TickLabelFormat of the axes (Matlab R2016b or later)
datetick(tickaxis,dateFormat) with dateFormat='HH' will also set the datetime format but the axis label will not include the full date references that shows using the x|y|ztickformat functions. Note: datetick is officially no longer recommended starting in R2024a.

Adam, you are right. I assumed the OP was using datenums. Still, datetick is not really the right way to manage the ticks in a datetime plot. Better to use the axis properties.
>> d = datetime(2021,11,24) + minutes(0:30:14400);
>> x = 1:length(d);
>> plot(d,x)
>> ax = get(gca,"XAxis")
ax =
DatetimeRuler with properties:
Limits: [Nov 24, 2021 Dec 04, 2021]
TickValues: [Nov 24, 2021 Nov 25, 2021 Nov 26, 2021 Nov 27, 2021 Nov 28, 2021 Nov 29, 2021 Nov 30, 2021 Dec 01, 2021 … ]
TickLabelFormat: 'MMM dd'
Show all properties
