joi-extension-date-outside 
Validate a date is outside a date range.
Example
const Joi = require('joi').extend(require('joi-extension-date-outside'))
const moment = require('moment')
const LAST_WEEK = moment().subtract(1, 'week').toDate()
const TODAY = moment().toDate()
const NEXT_WEEK = moment().add(1, 'week').toDate()
const NEXT_MONTH = moment().add(1, 'month').toDate()
const schema = Joi.date().outside({ from: LAST_WEEK, to: NEXT_WEEK })
schema.validate(TODAY) // Fail
schema.validate(NEXT_MONTH) // Success!Multiple ranges:
const Joi = require('joi').extend(require('joi-extension-date-outside'))
const moment = require('moment')
const LAST_YEAR = moment().subtract(1, 'year').toDate()
const LAST_WEEK = moment().subtract(1, 'week').toDate()
const TODAY = moment().toDate()
const TOMORROW = moment().add(1, 'day').toDate()
const NEXT_WEEK = moment().add(1, 'week').toDate()
const NEXT_MONTH = moment().add(1, 'month').toDate()
const NEXT_YEAR = moment().subtract(1, 'year').toDate()
const schema = Joi.date().outside([
{ from: LAST_WEEK, to: TODAY },
{ from: NEXT_WEEK, to: NEXT_MONTH }
])
schema.validate(LAST_WEEK) // Fail
schema.validate(NEXT_WEEK) // Fail
schema.validate(LAST_YEAR) // Success!
schema.validate(TOMORROW) // Success!
schema.validate(NEXT_YEAR) // Success!Using refs:
const Joi = require('joi').extend(require('joi-extension-date-outside'))
const moment = require('moment')
const LAST_WEEK = moment().subtract(1, 'week').toDate()
const TODAY = moment().toDate()
const NEXT_WEEK = moment().add(1, 'week').toDate()
const NEXT_MONTH = moment().add(1, 'month').toDate()
const schema = Joi.object().keys({
fromRef: Joi.date(),
toRef: Joi.date(),
date: Joi.date().outside({
from: Joi.ref('fromRef'),
to: Joi.ref('toRef')
})
})
schema.validate({
fromRef: LAST_WEEK,
toRef: NEXT_WEEK,
date: TODAY
}) // Fail
schema.validate({
fromRef: LAST_WEEK,
toRef: NEXT_WEEK,
date: NEXT_MONTH
}) // Success!
