Why people use date-fns
BR Business Days Calculator for Brazilian Logistics SLAs
With this Connector, that manual checking stops. Your agent gets a dedicated calculator that knows exactly which days are off in Brazil. You just ask for the date, and it gives you the correct business day every single time.
What Vinkius changes
You get 100% accurate Brazilian SLA dates without any AI hallucinations.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.
