The question says it all.

I have hunted high & low and don't see a way, but, before I hack the template I thought that I would ask here.

Just to make it clear - I want to be able to add some text at the top of the datepicker (which is a popup, if that makes any difference) such as "When is your birthday?".

There are many ways to do this if you follow this topic: Can you override specific templates in AngularUI Bootstrap? but I will just limit to two, one of which is CSS.

Template overriding:

Plunker Demo

The default file for the popup file is template/datepicker/popup.html, you just need to copy the contents of the file and append new code to it. The new code then will be wrapped inside <script id="template/datepicker/popup.html" type="text/ng-template"> directive and placed within <head>

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function($scope) {
  $scope.today = function() {
    $scope.dt = new Date();
  };
  $scope.today();

  $scope.clear = function() {
    $scope.dt = null;
  };

  // Disable weekend selection
  $scope.disabled = function(date, mode) {
    return (mode === 'day' && (date.getDay() === 0 || date.getDay() === 6));
  };

  $scope.toggleMin = function() {
    $scope.minDate = $scope.minDate ? null : new Date();
  };
  $scope.toggleMin();
  $scope.maxDate = new Date(2020, 5, 22);

  $scope.open = function($event) {
    $scope.status.opened = true;
  };

  $scope.setDate = function(year, month, day) {
    $scope.dt = new Date(year, month, day);
  };

  $scope.dateOptions = {
    formatYear: 'yy',
    startingDay: 1
  };

  $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
  $scope.format = $scope.formats[0];

  $scope.status = {
    opened: false
  };

  var tomorrow = new Date();
  tomorrow.setDate(tomorrow.getDate() + 1);
  var afterTomorrow = new Date();
  afterTomorrow.setDate(tomorrow.getDate() + 2);
  $scope.events = [{
    date: tomorrow,
    status: 'full'
  }, {
    date: afterTomorrow,
    status: 'partially'
  }];

  $scope.getDayClass = function(date, mode) {
    if (mode === 'day') {
      var dayToCheck = new Date(date).setHours(0, 0, 0, 0);

      for (var i = 0; i < $scope.events.length; i++) {
        var currentDay = new Date($scope.events[i].date).setHours(0, 0, 0, 0);

        if (dayToCheck === currentDay) {
          return $scope.events[i].status;
        }
      }
    }

    return '';
  };
});

angular.module("template/alert/alert.html", []).run(["$templateCache",
  function($templateCache) {
    $templateCache.put("template/alert/alert.html",
      "      <div class='alert' ng-class='type && \"alert-\" + type'>\n" +
      "          <button ng-show='closeable' type='button' class='close' ng-click='close()'>Close</button>\n" +
      "          <div ng-transclude></div>\n" +
      "      </div>");
  }
]);
.popup-header {
  text-align: center;
  font-weight: bold;
  padding: 10px;
}

CSS edit:

This is a non-standard way but it doesn't disturb your template structure anyway.

Plunker Demo

:before pseudo element in CSS supports content property to create text. Since you don't need to add anything other than header text/title, this is a fitting solution. Check the style.css file in the Plunkr to edit the text.

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function($scope) {
  $scope.today = function() {
    $scope.dt = new Date();
  };
  $scope.today();

  $scope.clear = function() {
    $scope.dt = null;
  };

  // Disable weekend selection
  $scope.disabled = function(date, mode) {
    return (mode === 'day' && (date.getDay() === 0 || date.getDay() === 6));
  };

  $scope.toggleMin = function() {
    $scope.minDate = $scope.minDate ? null : new Date();
  };
  $scope.toggleMin();
  $scope.maxDate = new Date(2020, 5, 22);

  $scope.open = function($event) {
    $scope.status.opened = true;
  };

  $scope.setDate = function(year, month, day) {
    $scope.dt = new Date(year, month, day);
  };

  $scope.dateOptions = {
    formatYear: 'yy',
    startingDay: 1
  };

  $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
  $scope.format = $scope.formats[0];

  $scope.status = {
    opened: false
  };

  var tomorrow = new Date();
  tomorrow.setDate(tomorrow.getDate() + 1);
  var afterTomorrow = new Date();
  afterTomorrow.setDate(tomorrow.getDate() + 2);
  $scope.events = [{
    date: tomorrow,
    status: 'full'
  }, {
    date: afterTomorrow,
    status: 'partially'
  }];

  $scope.getDayClass = function(date, mode) {
    if (mode === 'day') {
      var dayToCheck = new Date(date).setHours(0, 0, 0, 0);

      for (var i = 0; i < $scope.events.length; i++) {
        var currentDay = new Date($scope.events[i].date).setHours(0, 0, 0, 0);

        if (dayToCheck === currentDay) {
          return $scope.events[i].status;
        }
      }
    }

    return '';
  };
});
.date-picker + .dropdown-menu::before {
  content: "When is your Birthday?";
  font-weight: bold;
  position: relative;
  left: 25%;
}
.date-picker + .dropdown-menu li {
  margin-top: 5px;
