Just got my latest Verizon Wireless bill and it contains the following:
Beginning on September 1, all calls sent and received on national holidays - New Years
Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas
Day - will be billed according to the time of day, and the day of the week, they occur.
Airtime charges will apply to such calls in accordance with your calling plan. With calls
to other Verizon Wireless customers will remain free, and so will calls on nights and
weekends if your calling plan includes that feature. Please consult your Customer
Agreement for information about changes to your service.
