Woocommerce order date

I’ve done quite a bit of searching for this but cannot find an answer. We are using the WooCommerce Klaviyo extension and the transactional emails with your service. In the order confirmation email, I’m utilizing the {{ today }} variable to get the date of the order since it’s sent out immediately after their purchase. We also have cancelled order, refund order and order shipped transactional emails that can go out several days after the initial purchase date, so using the {{ today }} variable doesn’t make sense. I’ve looked through the data coming through for the order and searched everywhere for the actual order date variable, but it doesn’t seem to exist for WooCommerce. Am I wrong on this or just blatantly missing it? Any and all assistance on this would be greatly appreciated. Thank you.
