ADR (Average Daily Rate) and RevPAR (Revenue Per Available Room) follow the standard, industry-wide definitions used across hospitality benchmarking - the same numbers you'd get from STR or any other revenue-management tool, so they're directly comparable to your own historical figures, your accountant's own workings, and any market report you read.
ADR - overnight stays only
ADR = overnight room revenue ÷ overnight rooms sold
Day-use/hourly stays are excluded from both sides of this calculation. A day-use booking isn't equivalent to a room sold for the night, so including it - even at a fraction of a night - would distort ADR in a way no other hotel's ADR would be distorted, making your own number impossible to compare against anyone else's.
On a business date with no overnight stays at all (an all-day-use day, for example), ADR shows as "— (no overnight stays)" rather than a misleading ₹0 - there's real revenue that day, it's just not overnight room revenue, so an ADR of zero would be its own kind of misleading.
RevPAR - all room revenue, including day-use
RevPAR = total room revenue (including day-use) ÷ available rooms
Unlike ADR, RevPAR's denominator is available rooms, not sold rooms - so it's the right place for day-use revenue to show up. A room that earned money today, whether from one overnight guest or three day-use guests, contributed real revenue per available room.
Day-use has its own KPIs
Rather than blending day-use activity into ADR (which would need an invented "how many room-nights is a 6-hour stay worth" conversion, a number no two hotels would agree on), day-use performance is reported separately: slots sold, revenue, and average rate - both overall and broken down by slot length. Look for the Day-Use KPIs report alongside your other reports.
A note on historical numbers
This methodology has been correct in this system since it was introduced. If you're comparing figures from before that date against figures from after, be aware the earlier ones may have blended day-use revenue into ADR without excluding it from the "rooms sold" count - a discontinuity worth keeping in mind if you're building a long trend line across that boundary, rather than something silently smoothed over.
