Usage
This template is used to automatically generate and populate a template call for Template:Calendar for the month of January for the year specified. If no year is provided, the current year will be used.
Coding notes
- The template determines when a non-date specific event (e.g. fourth Thursday in November) occurs by using the following formula for each possible date that event could occur on:
{{#ifeq: {{#time:l|01 January {{{year|{{LOCALYEAR}}}}}}} | Tuesday |...
In this example, the template is checking to see if the first day of February was a Tuesday, and if so it will insert information about the event (represented by "..." in this example). If an event lasts for more than one day (e.g. Bright Nights) a #switch function is used instead, {{#switch: {{#time:l|01 January {{{year|{{LOCALYEAR}}}}}}} | Tuesday | Wednesday =...
however the logic is essentially the same.
- This template also uses an alternate formula where days of the week are assigned a value between 1 and 7, and then this value is added to some constant to determine whether or not an event is to occur on a given day:
|08 = {{#ifeq: {{#expr: 7+{{#switch: {{#time:l|01 January {{{year|{{LOCALYEAR}}}}}}} | Sunday = 7| Monday = 6| Tuesday = 5| Wednesday = 4| Thursday = 3| Friday = 2| Saturday = 1|}}}}| 8 |...
This format was abandoned in favor of the initial formula for its brevity.
