Ghatika

The day, from sunrise to sunrise

The Hindu day runs from one sunrise to the next: sixty ghaṭikās in eight prahars, four of daylight and four of night, each as long as the sky makes it today. The Kaal engine works it out here, in your browser, for the place you choose.

  • macOS, Apple siliconComing soon
Opening Manana the first time

Manana is not yet signed by Apple or Microsoft, so your computer asks before opening it the first time.

  • Mac: open the disk image and drag Manana to Applications. Open Manana once; when macOS stops it, go to System Settings, then Privacy and Security, and choose Open anyway. On older versions of macOS, Control-click Manana in Applications and choose Open.
  • Windows: run the installer. If Windows SmartScreen appears, choose More info, then Run anyway.
  • Linux: make the AppImage executable (in a terminal, chmod +x followed by the file name, or in your file manager's properties), then open it.

To check a download, compare its SHA-256 checksum with the one listed here, or with the checksum file.

For everyone

Open and free

  • Free, and not for sale

    No price, no subscription, no advertising. Hindavi Labs is non-commercial and stays that way.

  • Open source

    Every app is released under the GNU Affero General Public License, version 3 only (AGPL-3.0-only). Texts and data keep their own licences, listed in the credits below.

  • Neutral to every tradition

    No school, sampradāya or lineage is placed above another. Each text is given as its tradition keeps it, and each reader chooses their own path.

  • Private by default, local first

    Your work lives on your device first. This page has no analytics and no trackers, and it remembers only your choice of appearance, on your device.

How your data is kept

The Hindavi Labs account service holds only what an account needs: your name, how you sign in, and short check-ins from the apps so they know you are signed in. It receives nothing else.

Your reflections and your journal stay on your device in Manana. They leave it only when you choose to share something, with a study circle or for publishing.

The clock on this page is worked out in your browser. If you use your location, it stays on this page.

With thanks

Credits

The suite stands on the work of scholars, institutions and volunteers whose licences allow free sharing when their work is credited. If you reuse a text, keep its credit and licence with it. Each app also has its own credits page, text by text.
