Starbucks

I am preparing for my interview at the end of this month and here is my situation:

I held three part-time jobs in college from 1997-1999. I remember the names of the places I worked and the order that I worked at each place and that's about it.

Here is what the email says to bring "Complete employment history for last 10 years – Company name, address, phone number, Supervisor’s name (*HR Dept can be used) brief job description and the month and year of employment".

How big of a deal is it that I don't remember the exact months that I was employed at each part-time job? Should I just list the places of employment with approximate dates? I am probably overthinking all of this but all I have heard is the importance of having all your stuff together. Thanks for your help.
