Dutch Queen's day santiago (Santiago de Chile)

Hello everyone!
Next Monday, I will leave The Netherlands and I will arrive in Santiago on the 1st of May . In The Netherlands we celebrate Queen's day on the 30th of April. Therefore, I was wondering whether there will be a (delayed) celebration held in Santiago as well? If so, do I have to subscribe somewhere or can anyone join?
I look forward to hearing about it, so I will take some orange clothes with me.
Thanks in advance!

Adriaan
