SEO implications of changing Date/Time format on website

[PeteratS2]

Looking for some advice on an area that I can't seem to find much research about online.

Since starting our website, it's always been hosted in the UK and targeting UK visitors. That means we always had the date/time format of the website as DD.MM.YY for example.

We've now changed business focus and are targeting US visitors. We recently moved the site over to US hosting, and our web developers have instructed that we change to US date/time format (MM.DD.YY).

My question is, are there any implications on doing this from an SEO perspective? Obviously, all our historic blog posts will need to have their date updated from, for example, 9 July to July 9. Does this make any difference at all?

Anyone got any insights as to what best practice with this is?

Cheers.

Best practice is to do what is best for your consumers - so if targeting US consumers then recommend adopt the language and UX that best suits their needs.  From a seo perspective July 5, 2019 - is the US way...  for clarity - I always head to the New York Times or Washinton Post, and look at their structure for US.

Changing your date/time format will not affect your SEO in any way.
