And on Thursday, to honor the late Mister Rogers people in Pennsylvania are being challenged to be a good neighbor.
Governor Tom Wolf has proclaimed it as "1-4-3 Day."
He wants to encourage everyone to do something kind for someone else in memory of the beloved children's television personality.
Fred Rogers often used "1-4-3" as a way to say "I love you" - referring to the number of letters in each word.
To participate, every time you do something nice for someone, share it on social media using #143DayinPA and it will be counted in the Kindness Tracker.
If you need assistance, the Pennsylvania Department of Community and Economic Development set up a #143DayinPA Kindness Generator. Some of the ideas it suggests include "donate to a local children's fund," "give a friend or coworker a ride home," and "send a care package to troops."
Thursday is also the 143rd day of the year.
