Some promotions allow more than one entry. The exact rule might be daily, every 24 hours, weekly, monthly or a fixed number of entries per period.
Calendar day vs every 24 hours
These are not always the same. A calendar-day promotion can reset after midnight, while an every-24-hours promotion normally requires a full 24 hours from your previous entry.
Always follow the official rule
Fearless Competitions tracks the published entry limit, but the promoter’s terms are definitive.
