| 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. |
