📆 Years Months Days ⇄ Days Converter

Converts the number of days to year-month-day format (e.g. 1000 days = 2 years 9 months); or converts year, month and day values to a total number of days. The calculation uses the commonly accepted basis of 1 year = 365 days and 1 month = 30 days (the common approach in seniority and duration calculations).
