How to read the days-until answer
The headline measures the gap between today’s calendar date and the next World Heart Day date; it does not count today as an extra day. The live clock separately measures time remaining until the start of that date on your device. Time zones and daylight-saving changes can make the live hours different from calendar days multiplied by 24.
