bizdays MCP server

bizdays is a small helper that lets your AI do business-day math properly. It knows the real public holidays and the actual weekend days for each country, so it stops guessing. It is handy for anyone who plans deadlines, schedules, or payments across countries.

What this MCP server does

You ask your AI a question about working days, like how many workdays are left this month. Your AI passes the question to this helper. The helper checks the weekend rule for the country you named and looks up that country's public holidays. It then works out the answer and sends it back, along with which weekends and holidays it skipped. Your AI shows you the result in the chat.

What you can do with it

• Add or subtract working days from any date
• Count the working days between two dates
• Check whether a specific date is a working day
• Find the next working day after a date
• Find the previous working day before a date
• Look up a country's weekend rule and holiday setup

Try asking your AI

• “What date is 5 business days after December 22 in the UK?”
• “How many working days are in December for the US?”
• “Is Friday a working day in Saudi Arabia?”
• “What is the next business day after June 13 in Saudi Arabia?”

What it gives back to you

You get a clear answer in the chat: a date, a number of days, or a yes or no. Along with the answer, it tells you which weekends and named holidays it skipped, and which weekend rule it used. If a country's holiday data is not fully checked, it says so.
