World Amateur Radio Day (WARD) 2021 is Sunday, April 18. On that day in 1925, the International Amateur Radio Union (IARU) was formed in Paris. Today, the IARU is a worldwide federation of national amateur radio organizations. The IARU has chosen “Amateur Radio: Home but Never Alone” as its WARD 2021 theme, acknowledging the many ways throughout the COVID-19 pandemic that amateur radio has remained a welcome respite for its variety of activities and opportunities — even helping overcome online fatigue and social isolation. ARRL has information to help all radio amateurs plan for World Amateur Radio Day.
