Does this sentence is correct? Is This Sentence Correct?

This planning remains subject to minor changes in case of unforeseen problems/issues. Each column represents a week starting at date of 14th September 2015 and end at date of 5 February 2016. on September 14^th, 2015 and ending on February 5^th, 2105.

Cyrill, just a few minor changes is all. The main thing was the date format was incorrect for American English, the date format you used may have worked for British English, but the way I rewrote it is how the date would be written in American English. Also I had to add the word problems/issues to one of your sentences, either word could be used. If you have any questions please let me know.
