App Promotion on Christmastime and New Year

Recently I’ve finished with my social app and can release it.
Please, advice to the newbie: will it be hard to promote my app during Christmastime and New Year with installs and etc. or there is no difference between promotion on Christmastime and New Year and for example in February?
Would my app receive as many organic installs after promotion to survive or in case that many people are spending time with friends and relatives - they do not install as many apps as usual :confused:

People play a lot during that time and a lot will receive new tablets or phones on Christmas and will install new games on them - the problem is that during that time big developers throw all the money they can on marketing and it might be hard to get through.
