I'm making an appointment for next week, and I was going to suggest Tuesday, but then I thought, "May 1st - oh, I wonder if that's a holiday-feriado, I think so, let me look it up..."
So I go to the government's official page listing the mandatory feriados: https://www.argentina.gob.ar/interior/feriados
And on that page, I'm greeted with.....
A HUGE COUNTDOWN UNTIL THE NEXT FERIADO.
Screenshot in case the change it:
For those who don't read Spanish, in huge letters, it says: "6 DAYS UNTIL THE NEXT HOLIDAY"
I'm here alone but I burst out laughing outloud. The official government web page, counting down until the next holiday....
TIA
