To me, Presidents' Day is just another day off from work or school, or from one's daily routine since it's a federal holiday.
I never really got into the holidays that much. Of course I was into them more as a youngster, especially when I was in school. A lot of the holidays were celebrated in school. I think the last time I was ever excited or hyped to celebrate any holidays was when I was in art school.
As I got older they became less and less important to me. I tried to get into them if and when I had the time.
Why? I see the holidays as an excuse to get people to spend their money. Every year the media hypes the general public up around the holidays so they will spend money on holiday-related stuff and/or gifts. That's capitalism and consumerism at work.
People have more important things to do than to take part in any holidays.
I get into Thanksgiving, Easter which my family and I refer to as Resurrection Sunday, and Christmas for religious reasons since we are Christians.
We DON'T do Halloween for obvious reasons.
If you have time to celebrate and/or observe the holidays and get into them, good, more power to you.
I choose to express interest in certain holidays if I am in the mood to.
