+## Attributes
+
+Each `timer` entity provides a few useful attributes that describe its current configuration and runtime.
+
+- `duration`: Total configured length of the timer, in seconds or `HH:MM:SS`
+- `remaining`: How much time is left when the timer is active or paused; updates only when paused, restarted, or canceled
+- `finishes_at`: The timestamp when the timer will finish; available only when running
+- `restore`: Whether the timer will resume after a Home Assistant restart
+- 'editable': Whether the timer are manageable by UI 
+
+{% note %}
+The `remaining` value does not count down in real time. For dynamic countdowns or dashboards, rely on the `finishes_at` attribute.

+## Templates
+
+Timers can be combined with templates to show remaining time or end time dynamically.
+
+### Remaining time
+
+Create a template sensor that calculates how long the timer has left.
+It uses the `finishes_at` timestamp to compute the difference between now and the expected end.
+
+{% raw %}
+
+```yaml
+template:
+  - sensor:
+      - name: "Laundry Timer - Remaining"
+        state: >
+          {% set fin = state_attr('timer.laundry', 'finishes_at') %}
+          {% if fin %}
+            {% set s = (as_datetime(fin) - now()).total_seconds() | int %}
+            {{ (s if s > 0 else 0) | timestamp_custom('%H:%M:%S', false) }}
+          {% else %}
+            00:00:00
+          {% endif %}
+```
+{% endraw %}
+
+### End time
+
+A simpler version that shows when the timer will finish.
+With `device_class: timestamp`, it displays as a proper time value in the dashboard.
+
+{% raw %}
+
+```yaml
+template:
+  - sensor:
+      - name: "Laundry Timer - Ends at"
+        state: >
+          {% set fin = state_attr('timer.laundry', 'finishes_at') %}
