Oana!
...from April 10th, 2008 to April 30th, 2009.

Hi, Ian. The way you wrote is the american system. I wrote like that because I don't know which system I should use. Sometimes we use also in Romanian to write like that just to be very clear which is the month and which is the day, but if you advice me to change, I don't mind. Thank you

Well, if you prefer to use the numbers, we could say:
...from 10/4/2008 to 30/4/2009.
(We sometimes do it that way in English dates too, if it is clear which is the month and which the day.)
Or:
...from 10 April 2008 to 30 April 2009.
This is sometimes written with commas, like this:
...from 10 April, 2008 to 30 April, 2009.
You can finally also write it in the "American order" without the "th"s too, as:
...from April 10, 2008 to April 30, 2009.

Anyway, many possibilities, for you to choose from! Please make your choice, and then put it in your translation!
