On Linux, or any system that uses GNU date:

$ thedate=2019-08-15

$ date -d "$thedate" +'%B %e, %Y'

August 15, 2019

On macOS, OpenBSD and FreeBSD, where GNU date is not available by default:

$ thedate=2019-08-15

$ date -j -f '%Y-%m-%d' "$thedate" +'%B %e, %Y'

August 15, 2019

The -j option disables setting the system clock, and the format string used with -f describes the input date format (should be a strptime(3) format string describing the format used by your variable's value). Then follows the value of your variable and the format that you want your output to be in (should be a strftime(3) format string).

NetBSD users may use something similar to the above but without the -f input_fmt option, as their date implementation uses parsedate(3). Note also the -d option to specify the input date string:

$ thedate=2019-08-15

$ date -j -d "$thedate" +'%B %e, %Y'

August 15, 2019

See also the manual for date on your system.
