How to convert Years to Days?
Let's start from the beginning – how many Days are in a Years? The relationship is:
- 1 Year = 365 Days (approx.)
- 1 Day ≈ 0.00274 Years
To convert Years to Days, you need to multiply the value by 365.
Formula: Days = Years × 365
Note: This conversion excludes leap years. Leap years add an extra day (366 days in that year).
Step-by-Step Calculation
- Take the number of Years you want to convert (e.g., 3).
- Multiply that value by 365.
- The result is the value in Days. (Example: 3 × 365 = 1095 Days).
Include leap years? (365 vs 365.2425 days)
A “year” can mean different things depending on your use case:
- Common year: 365 days
- Leap year: 366 days (happens most years divisible by 4, with century exceptions)
- Gregorian average year: about 365.2425 days over long time periods
Tip: If you’re estimating roughly, 365 days/year is fine. If you’re modeling long timelines (many years), using 365.2425 days/year gives a closer average.
Need exact days? Use a date range
If you provide a start date and end date, you can calculate the exact number of days between them (including leap days automatically). This is more accurate than converting “years” when your timeframe crosses leap years.
Feature idea: Add a “Convert by dates” option: pick start/end dates → show exact days + weeks + months.
