The {{Infobox holiday}} template adds an infobox with data fields for defining a particular holiday.

For an annual holiday occurring on the same day each year:

holiday_name
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. The type parameter has this relation:
Type (param "type") Color
islam, islamic LightGreen
judaism, juda, jewish, jew LightSkyBlue
buddhism, buddhist, buddha PaleGoldenRod
christian, christ, christianity Lavender
asian, asian festival RosyBrown
secular DarkGray
national, international, local, group LightViolet
historical, cultural, patriotic, ethnic LightSalmon
pagan DarkKhaki
commercial Yellow
hindu, hinduism Orange
shinto, shintoism Light red
default LightSteelBlue
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.). Specific phrases for other rules are decoded in Template:Infobox holiday/date. Sample: "first Thursday after 18 April". If no value is given, the value of d:Property:P837 of the holiday's Wikidata item is displayed instead.
date२०२४
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 २०२४. At the end of २०२४, this will be replaced with dateआकृति:Future year, which will later be replaced with dateआकृति: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.)
image
This should be an image that represents the holiday. The value is just the simple target-name, not a full wikilink.
imagesize
The size of the image (default is 225px).
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
observedby
highly recommended - These are the people who celebrate/observe the holiday (e.g. Muslims and Islam, United States, people worldwide)
litcolor
This is the liturgical color of the day, if applicable to a religious holiday; or other color which is applicable to the holiday (e.g. green for Saint Patrick's Day)
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"
significance
This is a lengthier description of the holiday's significance
scheduling
define the how the date varies (not displayed). Sample value: "same day each year"
duration
time the holiday or observance last. Sample values: "1 day", "1 week", "3 days"
frequency
the frequency with which the holiday or observance re-occurs. Sample values: "annual", "weekly", "monthly"
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 dateआकृति:Future year, date२०२४, dateआकृति:Future year, etc. If you specify week_ordinal, then weekday and month are required also.
dateआकृति:Future year, dateआकृति:Future year
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.)
mdy
if set to a non-blank value, auto-formatted dates will be displayed in "month day, year" format instead of the default "day month year" order.
firsttime
first time/year the holiday was observed (if available)
lasttime
last time/year the holiday was observed (if no longer observed)
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.

Formulas for calculating occurrences

सम्पादन करी

Sample formulas used in Template:Infobox holiday/date:

For some holidays, this is still defined on the holiday page itself. For First Day of Summer, this would be:

|date                     = first Thursday after 18 April
|date{{LASTYEAR}}         = {{Weekday after date|{{LASTYEAR}}|April|18|Thursday}}
|date{{CURRENTYEAR}}      = {{Weekday after date|{{CURRENTYEAR}}|April|18|Thursday}}
|date{{NEXTYEAR}}         = {{Weekday after date|{{NEXTYEAR}}|April|18|Thursday}}
|date{{#time:Y|+2 years}} = {{Weekday after date|{{#time:Y|+2 years}}|April|18|Thursday}}
