School Bus Driver Appreciation Day is observed annually on the fourth Tuesday in April. This year it falls on April 28. School Bus Drivers’ Day originated in California. After it had been celebrated there informally for a while, the California legislature declared the day official. In 2009, they created the day to draw special public attention to school bus drivers in California for their enduring and exceptional contributions to students. The holiday seems to have spread after being established in the state to be commemorated casually.
National Pinup Day

National Pin-up Day is held every April 22 annually. Since the 1940s, pin-up has been an integral part of American culture.

They see the appeal in popular culture and have been delighting fans for a long time. The day comes with retro vibes that coincide with the origins of pin-up models. Most people, not just Americans, dress up in vintage or retro to celebrate the day.
