Although the @option{-p} option (also @option{--period}) is much more
versatile, there are other options to make the most common period
reports easier:

@table @option
@item -W, --weekly
Show weekly sub-totals.  Same as @samp{-p weekly}.
@item -M, --monthly
Show monthly sub-totals.  Same as @samp{-p monthly}.
@item -Y, --yearly
Show yearly sub-totals.  Same as @samp{-p yearly}.
@end table

@c      --dow              show a days-of-the-week report

There is one kind of period report cannot be done with @option{-p}.
This is the @option{--dow}, or ``days of the week'' report, which
shows summarized totals for each day of the week.  The following
examples shows a ``day of the week'' report of income and expenses:

@example
ledger --dow reg ^inc ^exp
@end example
