If you fork and change any code, please let me know, if it's useful for the general public, I'd love to add it!

If you find this module useful, and would like to contribute to the project, I appreciate the thought. Instead of giving to me, please donate to L'Arche Tahoma Hope at https://www.larchetahomahope.org/donate/ - in honor of Nancy Tyson. (Dedicate my donation checkbox). Nancy means the world to me. You don't have to notify me you have done so.

THANK YOU for your consideration.

This is a module for the MagicMirror² project.

This will create a mini-calendar with as many months as the user wants, assuming screen space is available. Screenshots are with config examples.

Clone this repository in your ~/MagicMirror/modules/ folder ( $ cd ~MagicMirror/modules/ ):

git clone https://github.com/BKeyport/MMM-Multimonth

Note: NPM INSTALL is no longer required. This module is proud to no longer use any external dependencies!

To use this module, add it to the modules array in the config/config.js file - shown options are defaults:

{
  module: 'MMM-Multimonth',
    position: 'top_left', // can be any of the postions
    config: { // Optional - will default to 3 months, with one previous and one next, vertical orientation.
    }
},

Full config options:

for the last three items: 0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday.

Remember the format for options:

option: value, Example: startMonth: -1,

Important: calNames is an array, please specify as such ["Main", "Sportsball", "Utility"] case is IMPORTANT.

instanceID: You can specify in custom.css different css for each instance. For example, if you add instanceID: "test", to your code, you can overide that instance with:

.MMM-Multimonth .month-header.test {
  background-color: blue;
  color: var(--color-header);
  font-size: var(--font-size-small);
  line-height: var(--font-size-small)+5;
  border-radius: var(--back-rounding);
}

To get events to feed to module, add the calendar module into your config.js.

Suggested settings at minimum:

		{
			module: "calendar",
			config: {
				broadcastPastEvents: true,
				calendars: [
					{
						url: <insert URL>,
						name: <name>,
					},
					//.... As many as you'd like .... 
				],
			}
		},

The module now can use the colors from the calendar module, default is the system color set (white)

The module now can use the symbols from the calendar module in big calendar mode.

Example (uses public calendar from the University of Washington):

{
	url: "https://gohuskies.com/calendar.ashx/calendar.ics",
	name: "Huskies",
	symbol: "paw",
	color: "#4B2E83",
},

I wanted a big calendar for the current month, and the solutions out there didn't do what I wanted, so here we are.

Big calendar mode will change two things in code.

The Week Number (if used) will become part of the first day of the week's spot.

Events will be summarized into a count and a symbol, and display below each day of the month.

To keep the CSS slim, I do not format anything differently, and it will break the constraints of the mini mode. Don't use if you're inexperienced in CSS. You will have to design your display yourself. If you have any questions, ask in the magic mirror forums. Myself or any of the CSS wizards will be happy to help you.

CSS is changed - please check all customizations. Old Elements, values, etc. have been deleted.

The following CSS code is all you need in custom.css if all you're changing is the colors and/or background edge rounding:

(Key changes here: "current" has been changed to "today", "background-week, color-week have been removed as redundant")

/* Defaults are shown */
.MMM-Multimonth .settings {
  --background-header: rgb(0, 128, 0);               /* for the month and year line, use green background */ 
  --background-dow: var(--color-background);         /* For the days of the week, use global background */ 
  --background-dowBlank: rgba(255, 255, 255, 0);     /* For the blank square if you use Week numbers */  
  --background-weekno: #808080;                      /* for the week number, use a grey background */ 
  --background-event: var(--color-background);		 /* Background for events, used in big mode only */
    
  --background-dimmed: var(--color-background);      /* For dimmed (previous/next month in current grid), use the global background color */
  --background-weekday: var(--color-background);     /* For normal days, use global background */ 
  --background-weekend: cornflowerblue;              /* For the days defined as your weekend, change the background to cornflowerblue */
  --background-today: Yellow;                        /* for the current day, change the background to yellow */ 

  --color-header: var(--color-text-bright);         /* for the header lines, use the global bright text color */ 
  --color-dow: var(--color-text);                   /* for the days of the week header, use the global text color */
  --color-dowBlank: rgba(255, 255, 255, 0);			/* For the blank square if you use Week numbers */ 
  --color-weekno: var(--color-text);                /* for the week numbers, use the global bright text color */

  --color-dimmed: var(--color-text-dimmed);         /* For dimmed (previous/next month in current grid), use the global dimmed text color */
  --color-weekday: var(--color-text);               /* For normal days, use global normal text */ 
  --color-weekend: var(--color-background);         /* For the days defined as your weekend, change the text to the background color */
  --color-today: var(--color-background);           /* for the current day, change the text to the background color */ 

  --back-rounding: 8px;                             /* Set the radius of the background rounded edges. See documentation for border-radius elsewhere */ 
  --alignment: center;                              /* Adjust the text alignment */ 
  --fontsize: var(--font-size-xsmall);              /* Set font size */
  --smallEventMarker: 3px;  						/* Event Marker size in pixels */
}

Notes on the colors above: You can use any colors you'd like. https://www.w3schools.com/cssref/css_colors.php is a list of accepted color names, or if you wanna make your own, https://www.w3schools.com/cssref/css_colors_legal.php. The above list is intended to be a sample, so I use different ways of doing legal colors. the "var" statements refer back to the master color list in Magic Mirror. You'll find a full list in main.css.

Many thanks to kirash for the inspiration with the monthly_calendar module, sdetweil and lavolp3 for the help in coding and CSS work. Without your help, this would just be a pipe dream.

Please, if you have any suggestions for improvement, let me know, I'm learning JS and CSS as I write this, and I dream of much bigger things.

Language Localization is controlled by the master language of MagicMirror.

Simply issue the following command in the MMM-Multimonth folder:

    git pull

then restart your mirror.

0.1 - Initial Release

0.2 - Change code to improve functionality, allow for some localization - will not move start of week yet, but will change languages with system.

0.25 - Fix code with temporary bodge so to refresh every hour to assure day changes sometime between midnight and 1 am.

0.3 - Removed bodge in 0.25, replaced with a simple refresh at midnight, no animation, as I find it annoying.

0.9 - Start of week now moves per moment.js. Note: at this point, module is almost everything I wanted. If I don't get any bug reports that I can control, I'm going to bump it up to 1.0 and call it good.

0.95 - Fix start of week issue. Had a calculation backwards. - Suggestion was made to optionally add week numbers to the system, still working on that.

0.99 - Major rewrite by Volker Wegert (Danke sehr!) - Implements everything I want, and I even understand the wizard level code he wrote.

1.00 - Minor changes to code/css to standardize look.

1.10 - Added leading and trailing months when 1 month is selected per user request.

1.20 - Added weekend highlight, default is off.

1.21 - Added weekend highlight for current day, so user could specify a different look for current day on weekend.

1.50 - Minor fixes

1.90 - Minor fixes/Remove EOL - Begin work on moving to a life without moment.js - Goal, no dependencies.

7 Sep 2022 - changing to date based versioning.

1 Oct 2022 - Completely removed moment.js from project. Returned to Beta Status due to lack of internationalization and start of week adjustments

4 Oct 2022 - Internationalization and Start of Week added back in. -- Note: I'm aware of a bug where the week numbers are showing an extra week. I'm redesigning the layout.

5 Oct 2022 - Fix bug in week numbers, fix extra week error.

12 Oct 2022 - Fix bug causing last day of month to fall off calendar if it's the same day as start of week.

24 Oct 2022 - Add config option for previous/next month display rather than forcing based on use.

29 Oct 2022 - Start Implementing streamlined CSS, add feature to move weekend around, documentation improvements.

4 Nov 2022 - Correct US/CA Week number calculation, add ISO calculation.

11 Nov 2022 - Changes:

• Temporary disabled US/CA week numbers, routine isn't consistent. I'm gonna rework it. Regardless of how it's set, you will use ISO week numbers.
• Rewrote javascript to match new knowledge, saving several lines of code and making more CSS sense.
• added classes for future features, prepped more things for major future planned feature.
• Streamlined CSS classes some more.
• Due to changes, css class "current_day_weekend" is no longer supported. It does nothing.

26 Nov 2022 - Changes:

• Added support for events from default calendar module.
• Changed the following css elements: day, dim, weekend, current, event, settings.
• Added new varable "--color-event" - which sets the color of the underline marking event on that day.

28 Nov 2022 - Added config option "eventsOn" to control event monitoring.

17 May 2023 - Added calNames - a way to control which calendars do what. Please see above.

16 Jul 2023 - Adjusted CSS to follow master font sizing from MagicMirror. Does not affect custom.css if used for this module.

18 Oct 2023 - Added CSS class "instanceID" to allow for more complex CSS. Yes, I'm still working on the module - just been busy. Added fontsize variable to defaults.

1 Dec 2023 - Basic changes to system to allow for a new feature (currently undocumented, need to go back through code to document due to being lazy and not writing down changes)

5 May 2024 - Fixed US Weeknumbers, among other bug fixes.

9 May 2024 - Adjusted README.md for new 3rd party list compatibility, plus capturing other changes.

8 Jun 2024 - MAJOR CSS re-write. Some values have changed, Some have been eliminated, some new.

18 Jun 2024 - Adjusted JS and CSS to make things line up better, found lots of little CSS bugs. Fully enabled color event handling.
