Install in Sevak

1. Open Settings → Gallery.
2. Choose Load gallery, then find Date calculator (Python).
3. Choose Install. Sevak checks the SHA-256 before it saves anything.
4. Allow it when Sevak asks (it shows the exact command).
5. Open the launcher and type days followed by a space.

Nothing is requested until you click, and no account is needed. A new listing reaches released builds with the next release.

Keyword to type

days

Requirements

• Python 3 on your command path

What to expect: runs a script

A script on your computer runs when you use the keyword, but only after you allow it. Sevak shows the exact command and asks once; if the files change it asks again. Read Gallery trust for how listings are checked.

Verify the download

Sevak does this for you on every install and refuses a file that does not match. To check it yourself, download the file and compare its SHA-256 with the value below.

Windows (PowerShell)   Get-FileHash -Algorithm SHA256 date-calculator.zip
macOS                  shasum -a 256 date-calculator.zip
Linux                  sha256sum date-calculator.zip

The hash is of the file as committed to the repository. Released builds of Sevak read the list pinned to their own release.
