Help with ADR dates.

[Aladdin73]

For some reason I can't add up my 180 days out correctly. We are going from Sept. 14-20. My wife normally takes care of this, but this trip is a surprise. Please help me find what date in March I need to book. I keep coming up with the 18th & the 26th. Thanks in advance for your help.
