If you have to wait for anything it will tell you how long and how many days you have to wait or waited for

★★★★★ Elvis Estrada · Aug 30, 2021

Useful to calculate the amount of force used in medical malpractice on a restricted biological reproductive system in multiple areas of study to fabricate and lose my reproductive organs illegally and cause severe developmental abuses in concept and programming the essential moral principles that a newborn needs to adapt adequately in modern society in order to open entry level workers for more sexual exploitation and child trafficking schemes to completely enforce a widespread origin genocide.

★★★★★ Devas jain08 · Dec 17, 2024

Give option to choose older version. Please I need old version. I am forced to uninstall the app. No more useful to me. I should have an option to have previous version. Sad to leave you after almost 10 years. Thank you. Miss You.

★★★★★ Leese Pat · Aug 12, 2023

Excellent. SIMPLE. ACCURATE. Just wished there was a business and public holiday calculator included!! To calculate vacation days. (Public holidays By country)

★★★★☆ ARACHNOID · Jan 2, 2026

This app' Days Calculator' is a good app. But something like the date format is not ISO 8601. I want ISO 8601 format.

★☆☆☆☆ Edward Idell · Dec 17, 2024

You ruined a great app. It no longer works properly. I don't have any days excluded but if I select a Sunday it won't take it it always moves it to Monday as the initial date for calculation. Why did you need to change it it was perfect as it was

★☆☆☆☆ Vinay Desai · Dec 12, 2024

Useless update.... Years date scrolling was needed as older version... Uninstalling

★★☆☆☆ BRV · Dec 22, 2024

Old version was very easy to use but now very difficult to use pls change to old version

★★☆☆☆ Joaquin Nina · Jun 27, 2021

It's easy to use, but too simple. No updates since 2017! Would be much better if it had the option to calculate working days, and also to input the amount of holidays between two dates.
