Because a company operating in two countries has two sets of public holidays, and most systems assume one. Working-day counts, accrual and delivery planning are then wrong for whichever group is not the default.
The set of non-working days that applies to a person, defined by location and assigned to the people it covers.
Calendars are defined per location and attached to people. Accrual, working-day counts and capacity all read the calendar that applies to each person rather than a single company default.
A delivery team split between the UK and India has different holidays in each. Capacity planning in Loop reflects both, so a deadline is not set on a day half the team is off.
It does not maintain public holiday dates for you. Calendars are entered or imported and reviewed each year.
Leave accrual, attendance expectations, and capacity in Loop. Payroll, where holidays affect a period's working days.
One primary calendar, with individual exceptions recorded as leave.
Yes, by defining a calendar at whatever granularity you need.
No. Dates are reviewed and rolled forward deliberately.
Fourteen days, every module, no card. Or half an hour with someone who will run it on your own records and tell you where it does not help.
