There are two possibilities for saving of generated HTML pages which need not always work, since they are dependent of the browser version and operating system:

File, Save as...: after saving, the saved page has to be checked, since it can be saved wrongly under certain circumstances.
View, Source: If then boxes or questionmarks appear, this saving function cannot be used.
If not, in the editor window, in the menu File the menu item Save as... has to be clicked and a filename has to be typed in double quotes (") with the file extension .html (sample: "My Calendar.html").
After saving the generated HTML file, the editor window can be closed, and the page can be checked.

The saved pages can be, of course, edited in every application (e.g. to add own notes or to change formattings) which supports HTML files - among other things, also Microsoft Word.

In WordPad, which is supplied with Windows, the Hebrew or Yiddish text can be edited in the HTML source code - the Hebrew respectively Yiddish letters are displayed correctly there.
