Well Thanksgiving can stay on the list, the bible says to be thankful in all things for this is the will of God.... Just because the date is pagan in origin doesn't mean you can't give thanks to the true God and Creator of Heaven and earth.
Yes I have heard the Christmas date was chosen by the Catholic Church to replace a pagan holiday, but you get a day off, every thing is closed, why not celebrate the birth of Christ with friends and family, Bible says Eph 5:16 Redeeming the time, because the days are evil. Or Col 4:5 Walk in wisdom toward them that are without, redeeming the time.
Use it as a witnessing tool, and celebrate a day off work.
Easter yes it is a pagan holiday of fertility, but that is probably the devils work as it takes place around the time of Passover and the death, burial and resurrection of Christ.
That is what Timothy is for "Study to Shew thyself approved unto God a work man who needeth not to be ashamed rightly dividing the word of truth. If your not Jewish, you don't need to celebrate Jewish Customs, if your Gentile you only need to follow what is outlined in the new testiment. However honouring or celebrating Jewish customs or holidays are optional.
