This is actually REALLY ambiguous. The difference between different interpretations is also a little bit more dramatic around this time of the year (February), even during a leap year because it's more than just off by one.
My assumption is that "a month from now" means "this same date next month" -- from today, March 20th.
So does "a month and ten days from now" mean a month from the day that is ten days from now? Or ten days from this day next month?
From today (February 20th), a month from the day that is ten days from now is April 1st because ten days from now is March 1st.
However, from today, ten days from a month from now is March 30th because a month from now is March 20th.
