Home of Advent Calendar


You are in a hurry?

OK, let's do it quickly!

git clone https://github.com/Devenet/AdventCalendar advent
cd advent/private
cp settings.example.json settings.json

Then edit the settings.json file to configure the application and set the year — or generate settings file and put it in the private folder.

To finish, just put your image files in the private folder; images named with the number of the day (such as 1.jpeg, 2.jpg, 3.png).
Supported formats are: JPG/JPEG, PNG, GIF.


Installation

Get the source

Download the last version on the releases page.

Or clone the repository

If you have git on your server, you can also just clone the repository with:

git clone https://github.com/Devenet/AdventCalendar advent

Configuration

Basic configuration

Copy the settings.example.json file on folder private to settings.json and edit it to configure the application.

The minimum required configuration file must contains:

{
  "title": "Advent Calendar · 2021",
  "year": 2021
}

Transform AdventCalendar into CountDownCalendar

If you want, you can also customize month, first day and last day which are used to display the period of days, but it's not really an AdventCalendar anymore ;-)

Just change the period with those 3 options:

{
  "month": 3,
  "first_day": 8,
  "last_day": 31
}

It will make a countdown calendar for March from the 8th to the 31th.

Full available options

Feel free to use the online settings file generator to easily build your settings.json file, and then put it into the private folder.

Picture per days

Add pictures

Put your photos in the private folder, and name them with the number of the day you want to illustrate. For example, for the 1st December, call your file 1.jpg or 1.jpeg.

Supported formats are: JPG/JPEG, PNG, GIF.

Be sure that the access to private folder is forbidden when browsing it!
For Apache configuration, be sure that a .htaccess file with the directive Require all denied is in and read.

Customize legend and title

Feel free to use the online calendar file generator to easily build your calendar.json file, and then put it into the private folder.

To add a title, a legend or a text on a day page, just rename calendar.example.json in folder private in calendar.json and add what you want to display.

For example:

{
  "6": {
    "title": "Saint Nicholas Day",
    "legend": "Berlin, March 2013",
    "text": "Lorem ipsum dolor sit amet, […]."
  }
}

Add a link

If you want that the image and legend point to a link, add the property link to the calendar.json:

{
  "8": {
    "legend": "Screnshot of Advent Calendar",
    "link": "https://www.devenet.eu/advent"
  }
}

A day with title, legend and text


Oups, problems?

  • All days are shown before Christmas: Check the syntax in settings.json or update the year.
  • Photo is not displayed: Be sure your photo is correctly named, like 3.jpg or 12.jpeg with the supported formats.
  • Title, legend or text are not displayed: Check the syntax of your calendar.json file.
  • Day is shown in late or advance: Configure the timezone of your server.
