13 is a special number because it is the 13th anniversary of the September 11 attacks.
September 11th, Americans across the nation will take a moment to reflect and pay their respects. These tributes offer an important focal point on this emotional day — and encourage remembrance, peace and community service. September 11th is not only a day of sadness and reflection — it’s also day for giving back. The 9/11 National Day of Service was founded to encourage the charitable spirit that is so present on that day.
