If your birthday is next month, then you're a very lucky person, according to the results of a recent study.
More than 40,000 people took part, and were asked to give their date of birth and whether they felt lucky or not.
People born between March and August thought they were luckier than those born between September and February, with May proving the "luckiest" month.
Scientists think the weather might have something to do with the results, but need to do more research to prove it.
