### 5/5 — Intuitive and Easy to Use

*2026-03-12*

App works great and is very intuitive to use.

### 5/5 — Great Tool! Highly recommended

*2023-03-04*

I rarely take time to write reviews, but this application has been a real timesaver for me. I use it frequently to find the date or week of the year, and also to calculate the number of days between events. It does what it was intended to do very well however, I do have one suggestion; it would be nice to convert backwards by entering the day of year and getting the calendar date as a result. Otherwise, a very useful tool and well-designed.

### 5/5 — Handy

I send a lot of timed correspondence orders and this program is very handy.  : )

### 5/5 — Really Handy Little App

*2021-04-16*

I use this app on a daily basis. If you have to work out specific dates often, I highly recommend this app.
