# Eones

## ✨ What is Eones?
Eones is a minimalist, dependency-free library for expressive, clear, and powerful date/time manipulation. Inspired by natural language semantics, it allows you to manipulate, compare, and transform dates as if they were living entities.
> *"That is not dead which can eternal lie, and with strange aeons even death may die."*
> — *Abdul Alhazred*, Necronomicon
### Philosophy
> **Eones is not a datetime replacement. It's a temporal reasoning layer.**
Eones exists to fill the gap between Python's low-level `datetime` and the need for semantic, calendar-aware date manipulation:
- Using **only the standard library** (Python 3.9+)
- Providing a **semantically rich and consistent API**
- Supporting modern timezone-aware design with `zoneinfo`
- Maintaining **modular and composable** architecture through clear separation of responsibilities (`Date`, `Delta`, `Range`)
**Eones is for:**
- Developers who want to reason about time semantically, not just manipulate timestamps
- Teams that want **zero external dependencies** for maximum portability
- Projects where **timezones, truncation, deltas and ranges** are central domain logic
---
## 📦 Installation
```bash
pip install "eones"
```
> If you're working with timezones on Windows or containers:
> ⚠️ Also install `tzdata`:
> ```bash
> pip install tzdata
> ```
---
## 🧪 Basic Example
```python
from eones import Eones
z = Eones("2025-06-15")
z.add(months=1, days=3) # -> add 3 days and 1 month
print(z.format("%Y-%m-%d")) # → 2025-07-18
print(z.diff_for_humans("2025-06-10")) # → in 5 days
print(z.diff_for_humans("2025-06-20", locale="es")) # → hace 5 días
```
---
## 🔍 Key Features
- ✅ **Zero external dependencies**: Pure Python (Python 3.9+)
- ✅ **Intuitive interface**: Simple, semantically rich and easy-to-use API
- ✅ **Modern timezone support**: Robust handling with `zoneinfo` (not `pytz`)
- ✅ **Flexible parsing**: Accepts multiple date formats automatically
- ✅ **Advanced temporal operations**: Deltas, ranges and semantic comparisons
- ✅ **Modular architecture**: Clear separation between `Date`, `Delta`, `Range` and utilities
- ✅ **Localization**: Support for multiple languages
- ✅ **Humanization**: Converts time differences to readable text
- ✅ **Complete type hinting**: Fully typed following PEP 561
- ✅ **Interoperability**: Compatible with Python's standard `datetime`
### Localization & Error Handling
You can add more languages by creating a new file in `eones/locales/` with the
translations for your locale. For example, `fr.py` for French.
Eones surfaces clear exceptions derived from `EonesError`. Invalid timezones
raise `InvalidTimezoneError`, while unparsable strings raise
`InvalidFormatError`.
