Christmas Star

Brazil
Timelimit: 1
Jupiter and Saturn are the largest planets in the Solar System. They will be aligned in December (2020), between the 16th and the 21st. This conjunction is a rare phenomenon known as 'Christmas Satar' and can be seen from various locations on Earth. Based on the orbital period (in Earth years - AT) of Jupiter and Saturn, your code should inform the end date of the next revolutions taking as a starting point December 21, 2020 and the number of days elapsed. Consider that Jupiter takes 11.9 AT to complete its orbit around the Sun and that Saturn takes 29.6 AT. Use integer values to define the number of days that have elapsed and remember to include the days of leap years.
Input
The entry will be an integer value N (0 < N <= 50) equivalent to the ordinal number of revolutions as of December 21, 2020. For example, N = 5 corresponds to the end date of the fifth revolution on each of the two planets .
Output
The output should show the number of days and (approximate) dates of the end of the revolution on the planets Jupiter and Saturn, respectively. Consider the following date format: yyyy - mm - dd
