I've been working on a couple of Rails side projects lately and I've found myself copying the same initializer to introduce some custom time formats to use with Time.to_fs:

This ultimately just lets me remember what these formats are called, and quickly reference them like this:

link_to datetime.to_fs(:human), date_path(date: datetime.to_fs(:ymd))

and get output like this:

<a href="/date/2024-03-31">March 31, 2024</a>
