@notablefi/fed-banking-days

A programmatic implementation of the Federal Reserve holiday schedule. Useful for providing timing estimates for Fed-processed transactions like ACH transfers.

Installation

Install using npm:

npm install fed-banking-days

Usage

Typescript:

import { nextBankingDay } from 'fed-banking-days';

or JavaScript:

const { nextBankingDay } = require('fed-banking-days');

nextBankingDay

The primary function, nextBankingDay, returns the Date that is the start of business (9am ET) on the next valid Fed banking day, as well as the latest holiday in between the given date and the next banking day.

For example:

…a Wednesday so the next banking day is tomorrow, Thursday.

> nextBankingDay(new Date('2022-06-15T06:00:00Z'))
[ 2022-06-16T13:00:00.000Z, undefined ]

…a Friday before a Sunday-holiday observed on Monday, so the next banking day is Tuesday.

> nextBankingDay(new Date('2022-06-17T06:00:00Z'))
[ 2022-06-21T13:00:00.000Z, 'Juneteenth National Independence Day' ]

Optionally, provide a minimum number of days to advance:

> nextBankingDay(new Date('2022-06-17T06:00:00Z'), 3)
[ 2022-06-23T13:00:00.000Z, 'Juneteenth National Independence Day' ]
> nextBankingDay(new Date('2022-06-17T06:00:00Z'), 10)
[ 2022-07-05T13:00:00.000Z, 'Independence Day' ]

useBusinessHours

By default, nextBankingDay will consider times after end-of-business (5pm ET) to be part of the next banking day, for more conservative estimates about ACH deposit availability. To disable this behavior and consider any time of a day to be part of that same banking day, pass useBusinessHours: false:

> nextBankingDay(new Date('2022-06-15T19:00:00-04:00')) // default behavior
[ 2022-06-17T13:00:00.000Z, undefined ]
> nextBankingDay(new Date('2022-06-15T19:00:00-04:00'), 1, { useBusinessHours: false })
[ 2022-06-16T13:00:00.000Z, undefined ]
