Rejuvenaide paste question - expiration?

I’m getting my foaling kit ready for this year and I’m trying to figure out what I need to buy to replace/supplement what I already have. I have several tubes of Rejuvenaide paste leftover from last year … but I can’t tell if they have an expiration? I found what looks like it might be an expiration date on the tube, but the numbers don’t make any sense. Does anyone know what the shelf life is for the paste? Thanks!
