Tkinter Datepicker (like the jQuery UI datepicker) (Python)

2017-06-19T18:22:01-07:00

Python recipe 580725 by Miguel Martínez López (calendar, datepicker, megawidget, tkinter). Revision 18.

It's based on ttkcalendar.py. But the internals are totally changed.I don't use for example the Treeview widget. I added more features also:

On mouse over, the day label changes the background
The selected day has an outstanding style
Added support for many hotkeys

These are the default bindings:

Click button 1 on entry: Show calendar
Click button 1 outside entry and calendar: Hide calendar
Escape: Hide calendar
CTRL + PAGE UP: Move to the previous month.
CTRL + PAGE DOWN: Move to the next month.
CTRL + SHIFT + PAGE UP: Move to the previous year.
CTRL + SHIFT + PAGE DOWN: Move to the next year.
CTRL + LEFT: Move to the previous day.
CTRL + RIGHT: Move to the next day.
CTRL + UP: Move to the previous week.
CTRL + DOWN: Move to the next week.
CTRL + END: Close the datepicker and erase the date.
CTRL + HOME: Move to the current month.
CTRL + SPACE: Show date on calendar
CTRL + Return: Set current selection to entry

Add days to a calendar date- Julian date (Batch)

2016-08-17T10:32:03-07:00

Batch recipe 580683 by Antoni Gual (calendar).

The trick to add days to a date is to convert the date to a serial, do a normal addition then convert the result back to a date. The serial I use here is the Julian day number used by the astronomers because its conversion formulas arewell documented. If you check the julian day number on internet the result can vary by a day, because julian days start at noon and i'm not making this distinction.

Liturgical Calendar Year class (Python)

2008-09-30T16:57:29-07:00

Python recipe 576518 by Martin Diers (calendar, church).

When initialized with a year, returns a class with a number of date attributes corresponding to common feasts of the western liturgical calendar. Number of Sundays after Epiphany and Trinity / Pentecost are also calculated, and stored in attributes. If the optional parameter v2 is set to True, the calendar will return a post-Vatican II calendar which changes the date of Transfiguration Sunday, and the number of Sundays after Epiphany. In either case, the pre-Lent Sundays and Sundays after Pentecost will be set.

Note: The year parameter is the year of the First Sunday in Advent - the beginning of the church year, and the resulting calendar thus ends in the following year.
