Comments on Date Calculator for Android

★★★★★ Pete Larsen · Nov 9, 2023

I like this little multi date and time calculator. It's easy to calculate days hours minutes even seconds if you wish. And so far just using the free version gives me all the information I need, highly recommend if you're looking for a quick easy time calculator with benefits....

★★★★☆ C Ananda Rao · Nov 13, 2025

Very nice. Please include option in settings to change the date format between MM/dd/YYY, dd/MM/YYY and YYY/MM/dd and other formats.

★★★★☆ Michael Fermanis · Nov 18, 2022

Overall, a good app. However, I use it mostly to calculate working days between dates. Unfortunately, I can find no way to set the dates of holidays, which can vary by country and company.

★★★★☆ Abhidhamma · Sep 4, 2021

A good calculator for most date related queries, solves my queries and I have been using this app for years now. Leaving a single star out because the ad placements are inconvenient, I understand the devs must earn for their effort, but I hope they find more efficient ad placement.

★☆☆☆☆ Jane Loh · Jan 29, 2023

Extra 1 day is added after calculation. Totally not correct. Makes app totally useless.

★★☆☆☆ D R · Jul 23, 2022

I loved the app but recently something has gone wrong with the output... for example it's saying 126 days is 18.429 weeks when it's clearly 18.0 weeks. It wasn't always like this, please fix it.

★★☆☆☆ Mike R. · Aug 20, 2020

Unreliable. Calculated 08-12-2020 + 5 working days including day yields 08-19-2020. Which is 6 working days.
