What is Elpatrons Date Calculator?
The date calculator can perform various date calculations:
Number of days between two dates
Number of workdays between two dates
Display of the weekday of a date
Date plus/minus X days
Date plus/minus X workdays
Date plus/minus X weeks/months
Calendar week to date
Start/end date of a calendar week of a year
Online date calculators already exist in abundance, so why another one?
For two reasons:
Try to find a date calculator that isn't completely infested with ads, tracking and cookies!
This annoyed me so much that I programmed my own.
Actually not me myself. This app was developed largely by AI following my instructions (Vibe Coding).
What else you should know
I have tried to make the app as accessible as possible to make it easier for people with disabilities to use.
This app doesn't spy on you, doesn't collect personal data and doesn't get on your nerves in any other way (hopefully!).
I have published the source code of this app on Codeberg you can view it, modify it or use it to run your own small date calculator.
The app runs on my small home server and is currently not designed for large visitor numbers.
I do not guarantee the functionality and calculation results. By the way, neither does the AI that programmed this.
If you find a bug or want an additional feature, you can write me an email (see mailto link in the footer)
Have fun with Elpatrons Date Calculator! Yours, M. Busche
