eom - end of month
som - start of month
'end of month' when today's date is the end of month returns today.
This behavior is different from some some of the other rules.
25 Apr April 25 this year (unless April 25 has passed, in which case it assumes next year)
I would expect End of Month to return the end of the next month if entered on the last day of the month.
