## Tools (as reported by the server, not verified)

- `datemath\_add`: Adds years/months/days to date. years/months are applied together with end-of-month clamping — e.g. 2026-01-31 + 1 month = 2026-02-28, not an overflowed 2026-03-03. days is then applied as plain calendar-day arithmetic.
- `datemath\_age`: Age in whole years as of asOf \(optional, defaults to the current UTC date\). A Feb-29 birthDate is treated as falling on March 1 in a non-leap asOf year.
- `datemath\_businessdays`: Counts days in \[from, to\] \(inclusive on both ends\) whose weekday is in weekdays \(default mon-fri\) and which aren't in holidays.
- `datemath\_dayofweek`: Day of the week for date: both the weekday name and its ISO 8601 weekday number \(1=Monday..7=Sunday\).
- `datemath\_diff`: Day difference between two YYYY-MM-DD dates: to minus from, in whole days. Negative if to is before from.
- `datemath\_leapyear`: Checks whether year is a leap year in the Gregorian calendar.
