New Safe Harbor 401(k)

Since the deadline for new Safe Harbor 401(k) plans falls on a weekend this year it is ok to start a new Safe Harbor Plan on October 2 this year? 

Is there a reason to not stretch to get it done, unambiguously, on time?

Do you have legal guidance saying that it is OK to go to the first business day after, if the normal deadline falls on a weekend?  By "legal guidance", I mean an ERISA attorney who would defend, before the IRS or otherwise in Tax Court, the validity of the new plan if, based on that attorney's legal advice, it was not started until the next following business day.

It comes down to your answer to the question "Are you feeling lucky?"

Not feeling lucky. In error I was thinking more of a filing deadline. Thanks for your time and input.  

January 1st sometimes fall on a weekend, but it always falls on a Holiday.  That doesn't change the fact that the plan year (for a calendar year plan) begins on that day :-)

Good Luck!
