Buttondown Documentation
Date formats are a hidden setting. Please send us an email (support@buttondown.email) if you'd like to change them on your account.
Date formats are, of course, a bit of a touchy subject. I'm an American and have to deal with the terrible hegemony of MM/DD/YYYY.
Buttondown offers a bit of flexibility to let you choose what date format you wish to present to your subscribers on the web archive. You can follow the key below for more information (or, if the prospect of dealing with date formatting at all is terrifying, you can ignore this section entirely.)
Note that this syntax is not the same as the syntax used to format dates using template variables; this is purely for customizing dates within your internal Buttondown dashboard. If you're looking to format dates in your emails, you'll want to use the date filter in your templates as showcased in that link.
