Worldwide Day of Play

Worldwide Day of Play is an annual event designed to encourage children and parents to turn off the television and play together, especially outdoors. The yearly event officially began on October 2, 2004, and has been broadcast on all US Nickelodeon channels: Nickelodeon, Nick GAS, Noggin, The N (now TeenNick), Nicktoons, Nick Jr. and NickMusic. The event is designed as a finale for Nick's six-month-long Let's Just Play campaign. In addition, Nick.com would also have special features for children to learn how to stay active and healthy.
Since the late 2000s, an international version of the event has also been broadcast on counterparts in Germany, Benelux, Greece, Poland and Russia.
General purpose.
The event encourages children to think about getting away from the TV and being physically active. Schools and educational organizations have also been encouraged to host events around this theme.
As it has since 2007 (until 2017), Nickelodeon will suspend programming on WWDoP across all of its TV channels–Nickelodeon, Nick Jr., Nicktoons and TeenNick– and websites from 12 p.m. to 3 p.m. (ET/PT) (where TV grid listings have this listed as "Off air" or "Worldwide Day of Play") urging kids to “get up, go outside and play.” According to Viacom, the owner of the Nickelodeon networks, millions of children and adults are expected to participate in "thousands of events in dozens of countries."
When the "Let's Just Play" campaign ended in September, Nickelodeon aired the finale during the last Saturday of September, the "Worldwide Day of Play". Nickelodeon and its sister channels suspend programming for three hours from 12 Noon to 3PM ET/PT. During the time there was no programming, a special message would appear on the screen. There was no "Let's Just Play" campaign in 2008, though the Day of Play was held that year.
Nickelodeon's 15th WWDoP took place on September 29, 2018, but there wasn't any "Off-Air" screens that year on the Nick networks.
