If you build a website and include a copyright date on the footer of each page, you're likely to want to keep this up to date every year.
If you've built A LOT of websites then updating this can be quite a time consuming process. To avoid a mad panic in the new year simply install the HD-Date plugin, enable it and replace the year with...
{year}
This can be within an article, module or part of the template's HTML code. When rendered to the screen any instance of {year} is replaced with the current year. Allowing you more time to recover from your new year celebratory hangover.
