Post Expirator query

Hello,

Is there are a way to customise the expiry date of each post? I need to publicise concert dates on a website but want these to disappear after the day of the concert. The concerts are all at different times and on different dates so they are not uniform.

I won’t to avoid any manual deleting and just set the delete expiry when the post is written.

Apologies if this is obvious but I am new to this.

Nick
