Larry has a condition where he always forgets his wedding anniversary. He knows that it is coming soon. His wife, Latisha, won't remind him. When Larry asked and she just rolled her eyes and said "If you can't remember it, why don't you just check your notes?"

You see, the last year that Larry forgot their anniversary he took notes so that he could remember next year.

The notes read:

- My anniversary is on the last day of the month.
- My anniversary month ends in "ember".
- My anniversary was 10 years ago.
- My anniversary month reminds me of the number 10.
- My anniversary month is dark.

Which month is Larry's anniversary?
