Date

Module to generate dates.

Overview

To quickly generate a date in the past, use recent() (last day) or past() (last year). To quickly generate a date in the future, use soon() (next day) or future() (next year). For a realistic birthdate for an adult, use birthdate().

For more control, any of these methods can be customized with further options, or use between() to generate a single date between two dates, or betweens() for multiple dates.

If you need to generate a date range (start-end), you can do so using either of these two methods:

• const start = faker.date.soon(); const end = faker.date.soon({ refDate: start });
• const [start, end] = faker.date.betweens({ from, to, count: 2 }); // does not work with tsconfig's noUncheckedIndexedAccess: true

Dates can be specified as Javascript Date objects, strings or UNIX timestamps. For example to generate a date between 1st January 2000 and now, use:

faker.date.between({ from: '2000-01-01', to: Date.now() });

You can generate random localized month and weekday names using month() and weekday().

These methods have additional concerns about reproducibility, see Reproducible Results.

Parameters

Name	Type	Default	Description
options?	{ ... } | { ... }	{}	The options to use to generate the birthdate.
options.refDate?	string | number | Date	faker.defaultRefDate()	The date to use as reference point for the newly generated date.
options.max	number		The maximum age/year to generate a birthdate for/in.
options.min	number		The minimum age/year to generate a birthdate for/in.
options.mode	'age' | 'year'		Either 'age' or 'year' to generate a birthdate based on the age or year range.
options.refDate?	string | number | Date	faker.defaultRefDate()	The date to use as reference point for the newly generated date. Only used when mode is 'age'.

Returns: Date

function birthdate(
