In a non-leap year, the first three months consist of January, February, and March. January has 31 days, February has 28 days, and March has 31 days. Therefore, the total number of days in these three months is 31 + 28 + 31 = 90 days.

233 days is about 7.65 months. (average months, or about 7 months, 20 days) It is only possible to estimate here as the months of the year have either 28, 30 or 31 days, then there is a leap month which has 29 days.
In a leap year, there are 186 days in the 31 day months and 180 days in the other months, so that is a difference of 6 days.
There are 30+31+30+31 = 122 days in the last four months of the year.
