# Class Calendar

java.lang.Object
com.codename1.ui.Component
com.codename1.ui.Container
com.codename1.ui.Calendar

All Implemented Interfaces:
  `Animation, Editable, ActionSource, StyleListener, Iterable<Component>`

public class Calendar extends Container implements ActionSource

Date widget for selecting a date/time value.

To localize strings for month names use the values "Calendar.Month" using the 3 first characters of the month name in the resource localization e.g. "`Calendar.Jan`", "`Calendar.Feb`" etc...

To localize strings for day names use the values "Calendar.Day" in the resource localization e.g. "`Calendar.Sunday`", "`Calendar.Monday`" etc...

Note that we recommend using the `com.codename1.ui.spinner.Picker` class which is superior when running on the device for most use cases.

    Form hi = new Form("Calendar", new BorderLayout());
    Calendar cld = new Calendar();
    cld.addActionListener((e) -> Log.p("You picked: " + new Date(cld.getSelectedDay())));
    hi.add(BorderLayout.CENTER, cld);
