I want to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format in Apex. Ex. "2016-05-20" should be converted to "2016-05-20T00:00:00-00:00". Any help/suggestion is appreciated.

I tried the "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" pattern and I am able to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format as given below-

    Date d = System.today(); Datetime myDT = datetime.newInstance(d.year(), d.month(),d.day()); String myDate = myDT.format('yyyy-MM-dd'T'HH:mm:ss.SSSXXX');

"YYYY-MM-DDThh:mm:ss-hh:mm" is ISO 8601

format. Check this link- https://www.w3.org/TR/xmlschema-2/#isoformats for ISO formats.

Refer http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

for formatting and parsing dates.
