The identifier `leapYears` was being detected by the spell checker tool as a misspelling of "leap years". The false positive is resolved by adding `leapyears` to the ignore list in the `.codespellrc` configuration file.

There was a problem hiding this comment.
getYear() fails for all days that match December 31st, except for the year 1970 and those where the next year is a leap one (brute-tested using Excel):
| Code | 1970/12/31 | 1971/12/31 | 1972/12/31 |
|---|---|---|---|
days |
364 | 729 (365+364) | 1095 (365+365+365) |
fullYears = days / 365 |
0 (364 / 365) | 1 (729 / 365) | 3 (1095 / 365) |
overDays = days % 365 |
364 (364 % 365) | 364 (729 % 365) | 0 (1095 % 365) |
leapYears = (fullYears - 2) / 4 |
0 ((0 − 2) / 4) | 0 ((1 − 2) / 4) | 0 ((3 − 2) / 4) |
if (leapYears > overDays) fullYears-- |
0 (No change) | 1 (No change) | 3 (No change) |
return 1970 + fullYears |
1970 (1970 + 0) | 1971 (1970 + 1) |
Fortunately, it can be easily fixed:
Suggested change
| int leapYears = (fullYears - 2) / 4; | |
| int leapYears = (fullYears + 1) / 4; |
