Angular 5 - how to make the period field type lowercase in DatePipe

you can just split your date to 2 parts:

{{ today | date : 'EEEE, MMMM d, h:mm' }} {{ today | date : 'a' | lowercase }}

UPDATE

Here is another simple way to achieve it, using built in date pipe and aaaaa matcher (which returns lowercase a or p):

<div>{{ today | date : 'EEEE, MMMM d, h:mm aaaaa\'m\'' }}</div>
