momentjs format returning date a day off?

I'm using momentjs to format my dates. However it is displaying the date a day off and I'm not sure why. Here is the code I'm using:

moment(date).format('MMMM do YYYY, h:mma')

where date = Sat May 05 2018 00:26:53 GMT-0400 (Eastern Daylight Time)

However the result is May 6th 2018, 12:26am - showing may 6 instead of may 5. Does anyone know why this may be? Thanks.

You're passing non-ISO string without specifying the format, which will result in a warning on the console, and may show the wrong date.

Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

Always pass the format as a preventive measure. Coming to your problem, to display the date correctly, you need to use Do specifier, instead of do. The former is for Day of Month but latter is for Day of Week.

var date = moment('Sat May 05 2018 00:26:53 GMT-0400 (Eastern Daylight Time)', 'ddd MMM DD YYYY HH:mm:ss');
console.log(date.format('MMMM Do YYYY, h:mma'))
