ಟೆಂಪ್ಲೇಟ್:Calendar date/doc

{{Calendar date/doc}} aka {{Moveable date}} is for displaying the calendar date of holidays or events that move annually, that do not have a fixed day and month of occurrence.

Examples include the Jewish new year Hanukkah which is based on a non-Gregorian calendar system. The June solstice wobbles celestially.

Usage

The template requires only two arguments, the holiday/event name (|holiday= or |event= are synonymous) and the year |year= in the Gregorian calendar.

Example:

{{calendar date |holiday=Rosh Hashanah |year=2019}}

Produces:

Optionally try |format=infobox in an infobox

Example:

{{Calendar date |holiday=Rosh Hashanah |year=2019 |format=infobox}}

Produces:

Options

Required

holiday or event

Name of an available holiday. Ex. |holiday=Rosh Hashanah or |event=Rosh Hashanah

year

Year of event. Ex. |year=2019

Options

df

Date Format options can be "dmy", "mdy" or "iso" (|df=dmy). Defaults are set in Module:Calendar date/events

format

Use |format=infobox in an infobox

cite

If set to anything (|cite=) a citation is added.

Adding or editing holidays

Holidays are configured in Module:Calendar date/events which has additional documentation and examples.

There are two holiday types: "calculator" and "localfile".

calculator - Moveable dates are determined with a calculator plugin. For example Rosh Hashanah uses the {{Hebrew year}} calculator:

datatype = "calculator"

datasource = "{{#time:Y-m-d|@{{Hebrew year/rhdatum|{{#timel:xjY|YYYY-11-1}}}}-1 days}}"

When the template runs, it replaces "YYYY" with the value of the |year= argument, then executes the datasource code. Calculators can be any available on Wikipedia, so long as it accepts a year value and returns a date in ISO format. All calculators are third-party plugins, the template does not do calculations.

localfile - When a calculator is not possible or unavailable, moveable dates can be stored in local files. For example with Tu BiShvat:

datatype = "localfile"

datasource = "Module:Calendar date/localfiles/Tu BiShvat"

The file Module:Calendar date/localfiles/Tu BiShvat contains a static list of dates.

Holidays with multiple aliases

If a holiday has multiple aliases, and it's desired the template support them with the |holiday= argument, create multiple entries in Module:Calendar date/events one for each name.

Dynamic dates

The |year= can accept templates.

For example, to show the current year for Tu BiShvat use {{CURRENTYEAR}}:

{{Moveable date |holiday=Tu BiShvat |year={{CURRENTYEAR}}}}

Produces

Other useful templates are {{LASTYEAR}} and {{NEXTYEAR}}.

Combined they can be used in infoboxes to fully automate updates, example from the Hanukkah infobox:

|date{{LASTYEAR}} = {{Moveable date |holiday=Hanukkah |year={{LASTYEAR}} |format=infobox |cite=}}

|date{{CURRENTYEAR}} = {{Moveable date |holiday=Hanukkah |year={{CURRENTYEAR}} |format=infobox}}

|date{{NEXTYEAR}} = {{Moveable date |holiday=Hanukkah |year={{NEXTYEAR}} |format=infobox}}

|date{{NEXTYEAR|2}} = {{Moveable date |holiday=Hanukkah |year={{NEXTYEAR|2}} |format=infobox}}

Offset date

An offset date can be calculated for a given moveable date using #time parser function.

For example, to show the date of the Friday following Ascension Thursday:

{{Moveable date |holiday=Ascension Thursday |df=dM |year={{CURRENTYEAR}}}}

{{#time: d M Y| {{Moveable date |holiday=Ascension Thursday |df=d |year={{CURRENTYEAR}}}} + 1 day}}
