<p>I repeated summer activities more than just one summer, but the Harvard supplement doesn't have room for you to put in more than just one date. How should I work around this?</p>
<p>It says “approximate dates of participations.” I would simply put the years for example 2005/2006.</p>
<p>You can put all your summer activities in the “Additional Information” section on the Common App. Just be sure to label them as such.</p>
