+
+Calculates the days between two dates based on the 360-day year.
+
+- Implementation of Excel's (or Number's) `DAYS360` / `TAGE360` formula in python.
+- Both EU and US methods of calculation are supported, with optional Excel bug compatibility.
+
+## Installation
+
+```
+pip install days360
+```
+
+## Usage
+
+```python
+from datetime import date
+from days360 import days360
+
+date_a = date(2022, 10, 2)
+date_b = date(2023, 11, 30)
+
+# supported methods: "US" (default), "US_NASD", "EU"
+days = days360(date_a, date_b, method="US")
+print(days)  # prints 418
+```
+
+## Planned
+
+- ISDA, PSA and SIA methods
