In the United States, tornadoes have occurred every single day of the year and strong or violent tornadoes (rated F2/EF2 or greater) have been recorded on multiple occasions each month. While this is not an exhaustive list of significant tornadoes, it includes tornadic events for each calendar day with an emphasis on storms that have occurred in North America. As tornadoes have occurred on every continent except Antarctica, significant tornadoes from other continents are also included on this list when they can be confirmed via reputable media or government agency.
