The ''eachday'' filter operator filters the current list to leave only the first tiddler that has a distinct value for a specified date field.

For example:

|!Filter String |!Description |
|`[eachday[created]]` |Returns a list of the first tiddler created on each distinct day |

The ''eachday'' operator can be used to group tiddlers. For example, the following wiki text creates a list of the number of tiddlers that were modified on each day:

<$list filter="[!is[system]eachday[modified]!sort[modified]]">

<$view field="modified" format="date" template="DD MMM YYYY"/>: <$count filter="[sameday{!!modified}]"/> modifications

</$list>
