    Specifying DAY:

    1) Implicitly: If no date is given, 'today' is assumed.

    2) Via a keyword: woli edit DAYNAME
    (Where DAYNAME can be:
    'today' or 't';
    'yesterday' or 'y')

    3) Via a date: woli edit DD[-MM[-YYYY]]
    (Use hyphens, dots or slashes to separate day/month/year.
    If year or month is not given, current year / current month is assumed.)

    4) Via days ago: woli edit ^DAYS
    (Where DAYS is a number of days ago. ^1 is yesterday, ^7 is a week ago etc.)
