In case someone else has been trying to make sense out of assorted IPL 2015 schedule on Sky Sports, I have created one public Google Calendar based on the schedule received from their Customer Care. You can search for it over Google calendars. The calendar name is "Sky TV NZ - IPL 2015 Schedule Details"

here is the link for ics file - http://goo.gl/Nmwpje.

Feel free to share.
