Calculate working days inside Claude Desktop

The `count_business_days` tool calculates the total number of working days between two dates, automatically skipping weekends. This is built for project managers who need to track actual execution windows without manual calendar counting. Just ask your agent to figure out the active working days for a sprint. It'll run the math instantly, giving you a clean number you can drop straight into your timeline.

Get precise calendar interval breakdowns

The `get_date_breakdown` tool provides a detailed breakdown of the time elapsed between two dates, separating the difference into years, months, weeks, and days. This stops the guesswork when you are drafting contracts or calculating exact project durations. Don't waste time with buggy online date counters. Your agent queries the tool to get the precise duration, delivering an accurate breakdown that's ready for any legal contract.

Verify global holiday conflicts instantly

The `verify_holiday_status` tool checks if a specific date is recognized as a national holiday in a given region, preventing scheduling mistakes across international teams. It checks regional calendars to ensure your deadlines do not land on a closed business day. Your agent uses this data to flag potential conflicts before you commit to a launch. It's an easy way to save yourself from setting a deadline on a major regional holiday.
