+# Business time utilities (add, diff, next open, in schedule)
+
+## What this solves
+Teams repeatedly reimplement the same business-time maths. This utility wraps `GlideSchedule` with four practical helpers so you can:
+- Add N working hours to a start date
+- Calculate working minutes between two dates
+- Find the next open time inside a schedule
+- Check if a specific time is inside the schedule window
+
+All functions return simple objects that are easy to log, test, and consume in Flows or Rules.
+
+## Where to use
+- Script Include in global or scoped app
+- Call from Business Rules, Flow Actions, or Background Scripts
+
+## Functions
+- `addWorkingHours(scheduleSysId, hoursToAdd, startGdt, tz)`
+- `workingMinutesBetween(scheduleSysId, startGdt, endGdt, tz)`
+- `nextOpen(scheduleSysId, fromGdt, tz)`
+- `isInSchedule(scheduleSysId, whenGdt, tz)`
+
+## Notes
+- The schedule determines both business hours and holidays.
+- `tz` is optional; if omitted, the schedule’s TZ or instance default applies.
+- All inputs accept either `GlideDateTime` or ISO strings (UTC-safe).
+
+## References
+- GlideSchedule API  
+  https://www.servicenow.com/docs/bundle/zurich-api-reference/page/app-store/dev_portal/API_reference/GlideSchedule/concept/c_GlideScheduleAPI.html
