Praytimes

PrayTimesRust is a powerful and versatile Muslim prayer time calculator implemented in Rust. This project is built upon the PrayTimes.org library, a widely recognized resource for accurate prayer time calculations. Whether you're developing a website, application, or any other digital platform, PrayTimesRust offers a seamless way to integrate accurate prayer time calculations for Muslims worldwide.

PrayTimes Kit

PrayTimesKit is a versatile toolkit for calculating Muslim prayer times and scheduling notifications around them. It is built on top of PrayTimes.org, a widely used prayer time calculation library.

Features

PrayTimesKit provides the following major features:

Accurate Prayer Time Calculations

• Calculates prayer times for any location using coordinates
• Supports several calculation methods like Muslim World League, ISNA, Egypt, Makkah, Karachi, Tehran, Jafari
• Highly configurable with customizable calculation parameters
• Support for Shia calculation methods

Prayer Time daemon

• Scheduled notifications for prayer times using system notifications
• Configure notifications to be triggered before/after any prayer time by a specified duration
• Notification text can contain dynamic info like prayer name, prayertime itself (which is different with the time that program runs because of the time diff), time difference

Prayer Time API

• HTTP API to get prayer times for a location and date
• Request JSON payload can configure calculation parameters, timezone, formatting
• Returns prayer times formatted as JSON

Usage

Configuration

The configuration file is a JSON file that specifies the location, calculation parameters, notification commands, and time formats.

Format

The format field specifies how prayer times should be formatted. It uses strftime syntax.

Default is %T which formats the time as HH:MM:SS.

Location

The location field specifies the location coordinates.

"location": {
  "longitude": 83.62,
  "latitude": 43.35
}

Parameters

The parameters field configures the calculation parameters.

There are two possible formats:

Specify Calculation Method

Use method to pick from a predefined calculation method:

"parameters": {
  "method": "Tehran"
}

Supported methods are:

• MWL - Muslim World League
• ISNA - Islamic Society of North America
• Egypt - Egyptian General Authority of Survey
• Makkah - Umm al-Qura, Makkah
• Karachi - University of Islamic Sciences, Karachi
• Tehran - Institute of Geophysics, University of Tehran
• Jafari - Shia Ithna-Ashari, Leva Institute, Qum

Customize Parameters

Specify the imsak, fajr, dhuhr etc parameters directly:

"parameters": {
  "imsak": 10,
  "fajr": 15,
  "dhuhr": 0,
  "asr": 1,
  "maghrib": 0,
  "isha": 10,
  "midnight": "Standard",
  "highLats": "NightMiddle"
}

Commands (configuration field)

The commands field contains the notification commands to run. Each command specifies:

• praytime - which prayer time to trigger on
• time_diff - minutes to add/subtract from the pray time
• cmd - the command to run

The command text can contain variables like $TYPE, $TIME, $DIFF which will be interpolated.

Tune

The tune field allows adjusting prayer times.and is a key-value pair of praytime names with a number the number is either negative or positive and is represented in minutes

Cli sub commands

PrayTimesKit provides the following commands:

serve

Starts the HTTP server for the prayer time API.

praytimes-kit serve

You can configure it using the PORT and HOST environment variables to run on a specific port or listen on specific ip.

You can also use Docker to run it:

docker run -p 3535:3535 -it basemax/praytimes:1.0

Or with Docker Compose:

version: "3"

services:

  praytimes:
    image: basemax/praytimes:1.0
    ports:
      - "3535:3535"
    environment:
      HOST: "0.0.0.0"

This runs the basemax/praytimes:1.0 Docker image, exposes port 3535, and sets the HOST env var so it listens on all interfaces.

Some additional Compose examples:

• Set a custom port:

ports:
  - "8080:3535"

daemon

Runs the prayer daemon based on a configuration file.

praytimes-kit daemon path/to/config.json

The configuration file specifies the location, calculation parameters, commands to run, and time formats.

Here is an example configuration:

{
  "location": {
    "longitude": 83.62,
    "latitude": 43.35
  },

  "parameters": {
    "method": "Tehran"
  },

  "format": "%T",

  "commands": [
    {
      "praytime": "dhuhr",
      "time_diff": 180,
      "cmd": "notify-send 'Adhan: Its $TYPE at $TIME + $DIFF'"
    },

    {
      "praytime": "maghrib",
      "time_diff": 180,
      "cmd": "notify-send 'Adhan: Its $TYPE at $TIME + $DIFF, the darkness is coming'"
    }
  ]
}

systemd service

You can define a systemd service for the praytimes daemon to control it using systemd

[Unit]
Description=praytimes daemon

[Service]
Environment="PRAYTIMES_LOG=info"
ExecStart=/path/to/praytimes-kit daemon /etc/praytimes/praytimes.json
Restart=always

then you can run

sudo systemctl enable praytimes;
sudo systemctl start praytimes;

calculate

Simple CLI to get prayer times for a location on a specific date. Supports text and JSON output formats

Gets prayer times for a location on a specific date.

praytimes-kit calculate --config path/to/config.json --date 2021-03-15

The configuration file contains the location details and calculation parameters. Note that you can use one configuration file for both daemon and calculate commands the unnecessary fields won't effect calculate command

help

simple cli to show praytimes for specific day

Usage: praytimes-kit calculate [OPTIONS] --config <CONFIG>

Options:
  -c, --config <CONFIG>  configuration file
  -d, --date <DATE>      date for calculation ( default is today ) [default: 2023-09-04]
  -f, --format <FORMAT>  strftime compatible format [default: %H:%M:%S]
  -j, --json             whether to output as json format or not
  -h, --help             Print help
  -V, --version          Print version

Integration

PrayTimesKit provides building blocks that can be easily integrated into other apps and services:

• Use the praytimes crate in your Rust project to calculate prayer times
• Call the HTTP API from any language to get prayer times
• Run the CLI on your desktop to get praytimes

Credits

PrayTimesKit is built on top of PrayTimes.org. The time calculation code is adapted from the original JavaScript library.
