Mistakes – Event Countdown Days Left Counter - Date Reminder Widget, Counting Clock Timer, and Calendar Wallpaper App Review

I checked out the app and it said 48 days until my birthday and I counted the days on the calender to make sure but it was off by 1 day. It was 49 not 48. Is there a possible way to change that mistake.
