Buenas Prácticas
- TODAY is excellent for calculating age, duration, or days remaining (e.g. `=A2 - TODAY()` calculates days until a deadline date in A2).
- If you need both the date and current system time, use `=NOW()` instead.
Errores Frecuentes
- TODAY is a volatile function. It can slow down large spreadsheets because it forces a recalculation of the entire sheet every time *any* cell changes.
- Do not use TODAY if you want a permanent timestamp that stays fixed.
