Hello Pablo, 

Thank you for purchasing Amelia, and for reaching out to us. 

You can set to see events in days from the past by adding this JS to the page:

<script>
window.ameliaBooking = {    pastEventsDays: 10,
}
</script>

It will show you up to ten days in the past. If you need it to show you more or fewer days, just change "10" to another number. And that is all.

Hope this helps.
