Parameters

Required

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.
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 date2025, which will later be replaced with date2026. 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.)

Optional

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 date2023, date2024, date2025, etc. If you specify week_ordinal, then weekday and month are required also.
date2023, date2025: 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

Sample formulas used in Template:Infobox holiday/date:

For First Day of Summer: first Thursday after 18 April:
{{Weekday after date|{{{year}}}|April|18|Thursday}}

See also: Template:Weekday after date
For Victoria Day (Scotland): last Monday before or on 24 May
{{Weekday before date|{{{year}}}|May|25|Monday}}

See also: Template:Weekday before date
For Sexagesima: second Sunday before Ash Wednesday (56 calendar days before Easter Sunday)
{{#invoke:Easter|Calculate|{{{year}}}|day=-56|format=F j}}

See also: Module:Easter

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}}
