Lahze

Lightweight package for formatting dates between jalali and gregorian. Supports both node and browser environments.

Usage

Basic usage

lahze can be initialized using 3 arguments: date, format of the date and locale.

After that lahze can manipulate and display date between locales easily.

import lahze from 'lahze';
 
lahze('1398/10/10', 'YYYY/MM/DD', 'fa').format('YYYY/MM/DD', 'en'); // 2019/12/31

• Date can be on of the following items:

  1. Instance of Date object
  2. String with a specific format
  3. Timestamp

  If date is not specified or null, it will be equal to today.

• Format accepted types are as followed:

  • YYYY: full year (4 digits).
  • YY: short year (last 2 digits).
  • MM: full month (2 digits).
  • M: short month (1-2 digit).
  • DD: full day (2 digits).
  • D: short day (1-2 digits).
  • HH: full hours (2 digits).
  • H: short hours (1-2 digits).
  • mm: full minutes (2 digits).
  • m: short minutes (1-2 digits).
  • ss: full seconds (2 digits).
  • s: short seconds (1-2 digits).
  • Supported delimiters are \, /, -, :.

  If format is not specified or null, it will be equal to whatever Date object accepts.

• Locale can be either fa or en (defaults en).

After initializing lahze with the desired arguments, you can easily manupulate date and display it with a specific format at the end.
