Sales open

Sales open and Sales close on a rental slot say when a slot can be booked. Both are measured backwards from the slot. If Sales open is empty, Default number of days before sales open from Rental → Settings is used.

Format	Example	Means
`[n]d`	`14d`	14 days before the slot.
`[n]w`	`2w`	2 weeks before the slot.
`[n]m`	`1m`	1 month before the slot. A month counts as 30 days.
`[n]h`	`2h`	2 hours before the slot starts, to the minute. Most useful for Sales close.
weekday	`ons`	The nearest Wednesday before the slot — or the same day, if the slot is on a Wednesday.
`[n].weekday`	`2.tir`	The second Tuesday backwards, counting from and including the slot’s day. A slot on a Tuesday opens 7 days before.
`…@[hour]`	`ons@18`	As above, but from 18:00. Works with all the formats except `[n]h`.
date	`2026-11-01`	A fixed date.
`idag`, `maks`	`maks`	`idag` (today) is the same day as the slot, `maks` (max) is 30 days before.

Without @[hour], sales open at the facility’s first opening hour that day, and close at the last one. The opening hours are in the standard row under Default times.

Weekdays can be written in Norwegian or English, the full name or the first three letters: onsdag, ons, wednesday and wed are the same.
