User Reviews

Overall, users praise Date Calculator for being easy to use and powerful for date math, including multi-date calculations. It’s appreciated as ad-free and useful for work. However, multiple reviews flag accuracy problems (extra day, incorrect month totals, 30-day month assumption) and request better date-format customization. The app is viewed positively and commonly recommended, with specific calls for improvement in precision and formatting flexibility.

Cons

Calculation accuracy issues (extra day added, total months wrong, and 30-day month assumption)
Date format customization missing or not easily configurable (need options like MM/dd/yyyy, dd/MM/yyyy, yyyy/MM/dd) and cross-format support
