This is not less important. On May 25th, 2023, the whole day and beyond the time the weather was awful, clouds, storms, and rain.
Because it is the last important patriotic day in Argentina before the presidential election this year 2023. The May Revolution was a direct reaction to Napoleon's invasion of Spain over Argentina.
In the year 1810, the revolution resulted in the first Argentine government, and independence from Spain.
It's the last May 25 and it was raining the whole day including May 26.
