Holidays Calculator, Version 3.12

http://www.robvanderwoude.com/holidays.php

Use the PHP version above, or download the HTA, to calculate holidays' dates.
The HTA version has some extra features, like localization, immediate refresh when a year is selected, and a Copy To Clipboard function.

Just pick a year from the list.
For the PHP version only: click the "Refresh" button to update all fields.

The Holidays Calculator will display the dates for several local and international holidays.
Besides showing the dates for the selected year, those of the previous and following year will be shown too.

For the HTA version only: the "Copy" button copies the results to the clipboard in CSV format.
Paste the results into Notepad, or a spreadsheet, for further processing.

For the HTA version only: the dates will always be displayed in the computer's date format.
The names of the holidays will be displayed in English by default.
On Dutch, French, German, Spanish, Portuguese or Italian computers, however, they will be displayed in their own language.
The default language choice can be overruled by using one of the following command line arguments:
/LANG:DE for German
/LANG:EN for English
/LANG:FR for French
/LANG:IT for Italian
/LANG:NL for Dutch
/LANG:PT for Portuguese
/LANG:SP for Spanish
If a configuration file exists, and it points to a translations file, the translations from the file will prevail.
The configuration file is a plain ASCII file named Holidays.cfg, located in the folder where this HTA is located.
It can contain 2 settings:

AutoUpdate=0

		Language=en

The language setting points to another ASCII file named Holidays.en which contains the translations for button labels and captions:

Ascension=Ascension

		BlameSomeoneElseDay=Blame Someone Else Day

		Christmas=Christmas

		Copy=Copy

		Copied=Copied

		Download=Download

		Easter=Easter

		GoodFriday=Good Friday

		GroundhogDay=Groundhog Day

		Halloween=Halloween

		HideNotification=Hide Notification

		NewYearsDay=New Year's Day

		Pentecost=Pentecost

		Sinterklaas=Saint Nicholas' Eve

		SintMaarten=Saint Martin's Day

		StPatricksDay=Saint Patrick's Day

		UpdateNow=Update Now

		Year=Year

This allows you to write your own translations.

If your HTA version is not the latest "stable" release, an update notification will be visible at the top of the window.
Clicking the "Download" button will open the Holidays download page in your default browser.
Clicking the "Update Now" button will overwrite the currently running HTA with the latest stable release, after a prompt for confirmation.
Setting AutoUpdate=1 in Holidays.cfg will update without any user interaction.

Note:

In some test cases, the "on-the-fly" update messed up extended ASCII characters (e.g. Norwegian), and I haven't managed to fix it yet, so using the "Download" button is the recommended course of action.
