Find how many seconds are left.
We know that 21 years contain:
21 × 31,536,000= 662,256,000 seconds
We started with 673,920,000 seconds. Subtract the seconds we've already used:
673,920,000 − 662,256,000= 11,664,000 seconds
That leaves 11,664,000 seconds after counting the 21 full years.

260 months = 21 years and 11,664,000 seconds
21 full years + 11,664,000 seconds left over.
