New Horizon Experience. This article describes the New Horizon Experience, which is available now. As of September 28, 2026, New Horizon is the default starting point on a computer or laptop. In the Horizon WebRef mobile apps for Android and iOS, New Horizon is already what you see. If you still have the older layout, choose Switch to New Horizon from the banner or your account menu. You can switch back to Legacy Horizon from that menu any time during the transition.
This article is for officials who belong to more than one organization and use the Availability Calendar. It explains how a save can stay with the organization you are signed into, or apply to every organization you belong to. Horizon remembers the switch, so the next time you open the calendar it is already set the way you left it.
If you only belong to one organization, you will not see these controls. For everyday calendar editing, see Understanding the Availability Calendar.
How multi-organization saves work
Each organization keeps its own availability calendar. When you change a day, Horizon can write that change only for the organization you are in right now, or for every organization you belong to.
The switch starts off, so a new save applies only to the organization you are signed into. That keeps one group's calendar from changing another group's days by accident. When you want the same change everywhere, turn the switch on before you save. Horizon keeps that choice. The next time you open Availability, the switch is still on until you turn it off, and it stays off until you turn it on again.
If you already chose a default under Personal Profile, the calendar opens with that choice. From then on, the switch on the calendar is what Horizon remembers.
Turning the switch on only affects saves you make after that. Existing days in other organizations stay as they are until you edit them again.
Save to all organizations on the calendar
Open Availability Calendar from Availability in the menu. On a phone the page title may read Availability. On a larger screen it reads Availability Calendar.
When you belong to more than one organization, look for the Multiple Organizations card. On a phone it sits below the month with Calendar Sources and Quick Toggle. On a larger screen it appears in the right-hand column. The switch reads Save new changes to all organizations. Turn it On before you change days if you want those new saves to apply everywhere. Leave it Off to update only the organization you are in.
On a computer, the same card appears beside the month.
The same wording can appear on Advanced Availability when you set a time window or a date range. Check it there too before you choose Save Availability. Changing it on either screen updates both, and Horizon remembers it for the next visit.
Can existing days be copied to another organization?
No. The all-organizations option only applies to future saves. It does not copy days that are already on the calendar into another organization. If you need the same pattern somewhere else, enter those days again while the save is set for all organizations, or edit that organization's calendar on its own.
If you still see the older layout
On a computer or laptop, the older legacy layout stays until you choose Switch to New Horizon from the banner or your account menu. This article describes the New Horizon screen. On the older layout, the checkbox at the top of the Availability Calendar applies new changes to all of your organizations, and the default still lives in Personal Profile under Preferences. Until that older layout is retired, use the English words you see there.
