Thanksgivukkah is putting a major squeeze on retailers.

Thanksgiving falls on Nov. 28 this year, the same day that Hanukkah begins. Given that the day after Thanksgiving, Black Friday, is the unofficial start to the holiday shopping season for most consumers, a late Thanksgiving translates into fewer holiday shopping days.

And those holiday shopping days are retail gold. Black Friday is so named because it is the first day of the calendar year that many retail stories start to make a profit, or move from the “red” to the “black.”

Eighty-five percent of small-business owners say that the holiday shopping period is just as -- or more important than -- last year, according to a survey by Manta, an online small-business community. Further, half of the survey's 2,000 respondents say that they expect holiday shoppers to spend less because of the U.S. government shutdown earlier this fall, which put a damper on consumer sentiment.

As a result, half of respondents are adjusting their sales strategy for maximum punch. Those who are changing their sales strategy are starting promotions sooner, reaching out more to customers on social media and increasing their email marketing.

"The holidays are the most important time of the year for my business and we've lowered our prices during this short holiday season to try attract more clients," said Samuel Rodriguez, co–owner of Ryan's Rest Dog Boarding and Training based in Farmington, Ark., according to a statement from Manta released earlier this week.

1. Focus on your local community. One advantage small-businesses have over any big-box competitors is that they know their consumers and the community of those consumers better than any major retailer can. Use local knowledge to speak directly to your local consumers.
