# Secondary calendar A player can have up to 2 calendars associated to it. We call them "primary" and "secondary" calendars. It is common to only have one calender, however there are some use cases where it is useful to have a secondary calendar. The secondary calendar is specified in the Player tab, on the details view: ![](/files/-M_W2aTSxyOJBJ0MK6cG) When a second calendar is specified, the player will now interleave the content of both calendars. So when the first calendar plays a playlist to the end, the next playlist will be picked from the second calendar. This is useful if for example your players belong to a big network where the HQ wants to push certain content to all the players in the network, but were every local shop wants to show their own content. The HQ can provide with the secondary calendar that all players are required to use, and so their content will be interleaved with the local shop calendar. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
