@rafalgiemza Errors not only occur in leap years, they also have problems in non leap years.

Source Code
There will always be a certain deviation when the number of months and days are converted from each other. Maybe we should return the specific number of days according to the specific month.
Do you have any ideas : )? thanks.

// bubble.js
export function daysToMonths (days) {
    // 400 years have 146097 days (taking into account leap year rules)
    // 400 years have 12 months === 4800
    return days * 4800 / 146097;
}
export function monthsToDays (months) {
    // the reverse of daysToMonths
    return months * 146097 / 4800;
}

Is this a problem in 2.25.3 ?
