Template:Components/doc

This template extracts numbers a, b, c from a string a-b-c, and a and b from a-b, and a from a. This can for example be applied to dates in the format y-m-d or d-m-y, months in the format y-m or m-y, and just years y, with a year range of ca. -1e14 to 1e14.

a-0-c gives the same results as a-c; also, not only 0-0-0 and 0-0 are not distinguished from each other, but also not from a single 0.

Examples

• "{{components|2008-9-17|1}}" gives "2008" [1]
• "{{components|2008-9-17|2}}" gives "9" [2]
• "{{components|2008-9-17|3}}" gives "17" [3]

• "{{components|17-9-2008|1}}" gives "17" [4]

#time

Function #time accepts dates like PHP's strtotime does. We consider here those with a dash. The examples show the resulting "y n d", which can be extracted separately too.

Full dates in the form d-m-y:

• {{#time:Y n j|17-9-2008}} → 2008 9 17 [25]

Full and partial dates in the form y-m-d, y-m, and y:

• {{#time:Y n j|2008-9-17}} → 2008 9 17 [26]
• {{#time:Y n j|108-9-17}} → 0108 9 17 [27]
• {{#time:Y n j|2008-9}} → 2008 9 1 [28] (current day of the month, not desired)
• {{#time:Y n j|2008}} → 2008 11 29 [29] (year interpreted as time, gives current full date, not desired)
• {{#time:Y n j|1999}} → 1999 11 29 [30] (current month and day of the month, not desired)

Thus #time is suitable for full dates only, and from the year 100 only:

• {{#time:Y n j|28-9-17}} → 2028 9 17 [31]

Applying #time to the result

After applying this template to a string representing a partial or full date, it is known whether it is in the form of a full date (existing or not). If so, the function #time can be usefully applied to check the existence of the date, to write it in a different format, and to find the weekday and the Gregorian serial day. If the year is outside the range that can be used by function #time, a conversion can first be applied, as is done in Template:Gsd.

Example result:

• Wednesday 17 September 2008, gsd = 733302
