The widget is initialized with the current month and year, but QCalendarWidget provides several public slots to change the year and month that is shown.

By default, today’s date is selected, and the user can select a date using both mouse and keyboard. The currently selected date can be retrieved using the selectedDate() function. It is possible to constrain the user selection to a given date range by setting the minimumDate and maximumDate properties. Alternatively, both properties can be set in one go using the setDateRange() convenience slot. Set the selectionMode property to NoSelection to prohibit the user from selecting at all. Note that a date also can be selected programmatically using the setSelectedDate() slot.

The currently displayed month and year can be retrieved using the monthShown() and yearShown() functions, respectively.

A newly created calendar widget uses abbreviated day names, and both Saturdays and Sundays are marked in red. The calendar grid is not visible. The week numbers are displayed, and the first column day is the first day of the week for the calendar’s locale.

The notation of the days can be altered to a single letter abbreviations (“M” for “Monday”) by setting the horizontalHeaderFormat property to SingleLetterDayNames . Setting the same property to LongDayNames makes the header display the complete day names. The week numbers can be removed by setting the verticalHeaderFormat property to NoVerticalHeader . The calendar grid can be turned on by setting the gridVisible property to true using the setGridVisible() function:

../../_images/qcalendarwidget-grid.png 
calendar = QCalendarWidget()
calendar.setGridVisible(True)

Finally, the day in the first column can be altered using the setFirstDayOfWeek() function.

The QCalendarWidget class also provides three signals, selectionChanged() , activated() and currentPageChanged() making it possible to respond to user interaction.

The rendering of the headers, weekdays or single days can be largely customized by setting QTextCharFormat’s for some special weekday, a special date or for the rendering of the headers.

Only a subset of the properties in QTextCharFormat are used by the calendar widget. Currently, the foreground, background and font properties are used to determine the rendering of individual cells in the widget.

class HorizontalHeaderFormat

This enum type defines the various formats the horizontal header can display.

Constant

Description

QCalendarWidget.SingleLetterDayNames

The header displays a single letter abbreviation for day names (e.g. M for Monday).

QCalendarWidget.ShortDayNames

The header displays a short abbreviation for day names (e.g. Mon for Monday).

QCalendarWidget.LongDayNames

The header displays complete day names (e.g. Monday).

QCalendarWidget.NoHorizontalHeader

The header is hidden.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property dateEditAcceptDelayᅟ: int

This property holds the time an inactive date edit is shown before its contents are accepted.

If the calendar widget’s date edit is enabled , this property specifies the amount of time (in milliseconds) that the date edit remains open after the most recent user input. Once this time has elapsed, the date specified in the date edit is accepted and the popup is closed.

By default, the delay is defined to be 1500 milliseconds (1.5 seconds).

Access functions:
property dateEditEnabledᅟ: bool

This property holds whether the date edit popup is enabled.

If this property is enabled, pressing a non-modifier key will cause a date edit to popup if the calendar widget has focus, allowing the user to specify a date in the form specified by the current locale.

By default, this property is enabled.

The date edit is simpler in appearance than QDateEdit , but allows the user to navigate between fields using the left and right cursor keys, increment and decrement individual fields using the up and down cursor keys, and enter values directly using the number keys.

Access functions:
property firstDayOfWeekᅟ: Qt.DayOfWeek

This property holds a value identifying the day displayed in the first column..

By default, the day displayed in the first column is the first day of the week for the calendar’s locale.

Access functions:
property gridVisibleᅟ: bool

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

This property holds whether the table grid is displayed..

qcalendarwidget-grid1

 
calendar = QCalendarWidget()
calendar.setGridVisible(True)

The default value is false.

Access functions:
property horizontalHeaderFormatᅟ: QCalendarWidget.HorizontalHeaderFormat

This property holds the format of the horizontal header..

The default value is ShortDayNames .

Access functions:
property maximumDateᅟ: QDate

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

This property holds the maximum date of the currently specified date range..

The user will not be able to select a date which is after the currently set maximum date.

../../_images/qcalendarwidget-maximum.png 
calendar = QCalendarWidget()
calendar.setGridVisible(True)
calendar.setMaximumDate(QDate(2006, 7, 3))

When setting a maximum date, the minimumDate and selectedDate properties are adjusted if the selection range becomes invalid. If the provided date is not a valid QDate object, the setMaximumDate() function does nothing.

The default maximum date is December 31, 9999 CE. You can restore this default by calling clearMaximumDate() (since Qt 6.6).

setDateRange()

Access functions:
property minimumDateᅟ: QDate

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

This property holds the minimum date of the currently specified date range..

The user will not be able to select a date that is before the currently set minimum date.

../../_images/qcalendarwidget-minimum.png 
calendar = QCalendarWidget()
calendar.setGridVisible(True)
calendar.setMinimumDate(QDate(2006, 6, 19))

When setting a minimum date, the maximumDate and selectedDate properties are adjusted if the selection range becomes invalid. If the provided date is not a valid QDate object, the setMinimumDate() function does nothing.

The default minimum date is November 25, 4714 BCE. You can restore this default by calling clearMinimumDate() (since Qt 6.6).

setDateRange()

Access functions:
property navigationBarVisibleᅟ: bool

This property holds whether the navigation bar is shown or not.

When this property is true (the default), the next month, previous month, month selection, year selection controls are shown on top.

When the property is set to false, these controls are hidden.

Access functions:
property selectedDateᅟ: QDate

This property holds the currently selected date..

The selected date must be within the date range specified by the minimumDate and maximumDate properties. By default, the selected date is the current date.

See also

setDateRange()

Access functions:
property selectionModeᅟ: QCalendarWidget.SelectionMode

This property holds the type of selection the user can make in the calendar.

When this property is set to SingleSelection , the user can select a date within the minimum and maximum allowed dates, using either the mouse or the keyboard.

When the property is set to NoSelection , the user will be unable to select dates, but they can still be selected programmatically. Note that the date that is selected when the property is set to NoSelection will still be the selected date of the calendar.

The default value is SingleSelection .

Access functions:
property verticalHeaderFormatᅟ: QCalendarWidget.VerticalHeaderFormat

This property holds the format of the vertical header..

The default value is QCalendarWidget::ISOWeekNumber.
