I’m trying to edit our packing slip for Shopify so order.created_at no longer displays in military time and instead shows standard. Is there any way to code this?

I know html would allow something like this:

if (h = 13) {h = 1}
if (h = 14) {h = 2}
if (h = 15) {h = 3}
if (h = 16) {h = 4}
if (h = 17) {h = 5}
if (h = 18) {h = 6}
if (h = 19) {h = 7}
if (h = 20) {h = 8}
if (h = 21) {h = 9}
if (h = 22) {h = 10}
if (h = 23) {h = 11}
if (h = 24) {h = 12}

Is this plausible for it to return with am/pm instead of military?

I don’t even know what to try.
