+## Date
+
+The KNX date platform allows to send date values to the KNX bus and update its state from received telegrams. It can optionally respond to read requests from the KNX bus.
+
+<div class='note'>
+
+Date entities without a `state_address` will restore their last known state after Home Assistant was restarted.
+
+Dates that have a `state_address` configured request their current state from the KNX bus.

+</div>
+
+<div class='note'>
+
+DPT 11.001 covers the range 1990 to 2089. Year values outside of this range are not allowed.
