I got married at 11:11am on 4/20/15. Can someone give me a breakdown of months (6) weeks (26) days (180) hours, minutes and seconds.?

I want to make her something using those details and give it to her at 11:11 on 10/20/15. I am just not good with math.

Assuming I'm understanding your question correctly.
The difference between those two times will be:
6 months or
6 1/7 weeks (the two dates fall on different days of the week) or
183 days or
10,980 hours or
658,800 minutes or
39,528,000 seconds
