A really simple website (and node.js script) for adding or subtracting time. Want to try the website? Click here!
You can find more information about the node.js script by going in the "node" folder (click here!)
The website is really easy to use. When opened, you find a selector, where you can choose if you want to add seconds, minutes or hours. Put the number in the textbox and then click to add. You'll see the result below. You can choose if you want to view the result in seconds, minutes or hours.
If you prefer, you can also have a separated textbox for hours, minutes and seconds. Enable the checkbox and they'll appear.
This website will automatically adapt to the default theme of your browser or device. If you want, you can switch from light to dark mode (or viceversa) by clicking the moon / sun image at the right of the title.
