As it's a non-standard format (hours exceed 23) I think you'll need to do the addition manually. Try this (note that need to add some error checking): string[] items = textBox1.Text.Split(':'); int hours = int.Parse(items[0]); int mins = int.Parse(items[1]); int secs = int.Parse(items[2]); string[] itemsAdd = textBox2.Text.Split(':'); int hoursAdd = int.Parse(itemsAdd[0]); int minsAdd = int.Parse(itemsAdd[1]); int secsAdd = int.Parse(itemsAdd[2]); int secsResult = (secs + secsAdd) % 60; int minsPlus = (secs + secsAdd) / 60; int minsResult = (mins + minsAdd + minsPlus) % 60; int hoursPlus = (mins + minsAdd + minsPlus) / 60; int hoursResult = hours + hoursAdd + hoursPlus; textBox3.Text = String.Format({0:D2}:{1:D2}:{2:D2} hoursResult minsResult secsResult)
