This is the most common holiday name, which appears at the top of the infobox. It should almost always be the name of the article.
type
The type of the holiday, for example national, judaism, islamic etc..
begins
required for multi-day holidays - This is the starting date for a multi-day holiday.
ends
required for multi-day holidays - This is the ending date for a multi-day holiday.
date
required for single-day holidays - This is the date of a single-day holiday. (If you use the week_ordinal/weekday/month parameters below, date will default to a phrase like "First Sunday in January". Otherwise it has no default and is required.)
date2024
highly recommended for holidays that don't stay on the same Gregorian date - This is the Gregorian date on which the holiday will occur in 2024. At the end of 2024, this will be replaced with dateTemplate:Future year, which will later be replaced with dateTemplate:Future year. Therefore, it's a good idea to specify the Gregorian date for a few future years. (Not necessary if week_ordinal/weekday/month are specified instead.)
highly recommended - These are the people who celebrate/observe the holiday (e.g. Muslims and Islam, United States of America, people worldwide)
longtype
This is a lengthier description of the type, for example if there are two types that could be defined, for example "Cultural, Historical, Islamic"
image
This should be an image that represents the holiday.
caption
This is a caption that describes the image.
official_name
This should contain the official name of the holiday if it is not the holiday_name; this can also be the name of the holiday in its original language
nickname
This should hold any nicknames, alternatives, and translations for the holiday_name or official_name
week_ordinal, weekday, month
For days that are observed on the same day of the same week every year, these specify the week (week_ordinal), day of the week (weekday), and month. If you use these, you no longer have to specify dateTemplate:Future year, date2024, dateTemplate:Future year, etc. If you specify week_ordinal, then weekday and month are required also.
recommended for holidays that don't stay on the same Gregorian date - The template will display the previous and next year's dates along with that of the current year, if they are provided. Again, it's a good idea to provide dates for a few years further into the future as well. (Not necessary if week_ordinal/weekday/month are specified instead.)
celebrations
This contains the celebrations that occur on the holiday.
observances
This contains essentially the same thing as the celebrations attribute. However, the word observances is used. This may be more appropriate than celebrations when referring to prayer or more solemn observances. Most likely, you will not need both celebrations and observances.
relatedto
This contains holidays that relate to the current holiday.
