## Solution.

48 months is exactly 4 years. 48 weeks is $48 \times 7=336$ days. Together with another 48 days, this totals 384 days, which is 1 year and another 18 or 19 days, depending on whether the year is a leap year. In any case, the remaining days plus another 48 hours add up to less than one year. In total: $48+4+1=53$.
