Formatting Dates
This feature allows you to format dates into human-readable strings using a specified format string. The format string can include various placeholders for different parts of the date.
const d3 = require('d3-time-format');
const formatTime = d3.timeFormat('%B %d, %Y');
console.log(formatTime(new Date())); // Outputs: 'October 05, 2023'
Locale-Specific Formatting
This feature allows you to create locale-specific date and time formats. You can define custom formats for dates, times, periods, days, and months, which can be used to format dates in a way that is specific to a particular locale.
const d3 = require('d3-time-format');
const locale = d3.timeFormatLocale({
dateTime: '%x, %X',
date: '%-m/%-d/%Y',
time: '%-I:%M:%S %p',
periods: ['AM', 'PM'],
days: ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'],
shortDays: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
months: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
shortMonths: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
});
const formatTime = locale.format('%A, %B %d, %Y');
console.log(formatTime(new Date())); // Outputs: 'Thursday, October 05, 2023'
