Today is New Year of the Trees also known as Tu Bi'shvat (which is the date ט״ו בשבט‎). Growing up in school, it was the day you planted trees in Israel (so we donated a few bucks to make that possible, since we couldn't physically go to Israel and plant them ourselves). Here is a picture I found on Flickr of kids planting trees (not sure it is in Israel, but you get the point):

Tu Bi'shvat

Many Jews will eat a platter of dried fruits including the seven species associated with Israel, Wheat, Barley, Grapes, Figs, Pomegranates, Olives and Dates. Personally, I do not like dried fruit, so I skip it. :)

You can learn more about the day on Google, if you like.
