org-agenda - exclude default international holidays?

Question

my org-agenda setup is pretty default.

How can I make it exclude default international days?

For example,

Sunday 29 May 2022
Diary: Ascension of Baha'u'llah

Monday 30 May 2022
Diary: Memorial Day

I'm now sure where this setting is coming from and how to disable it?

Answer 1

Looks like you just need to set org-agenda-include-diary variable to nil.

See this answer if you need more control over which holidays are displayed there.
