Good Day,
After getting the days with above formula, how about multiply the days by 24, 1440 or 86400 to get the total hours, minutes or seconds until the next birthday in Excel?

Good Day,
The date within the upcoming ten days is your next birthday, so after getting current date with formula =TODAY(), please use the formula =DATEDIF(B2,C2,"d") (B2 is the cell contains the current date, C2 contains the birthday of your own) directly to get the remaining days until next birthday.
