epok

• Epok extends Date() functionality with easy to use functions and Chai-like syntax
• No external dependencies
• Since this is just a wrapper around Date(), all leap year calculations are taken care of for you

API

Epok()

Creates a Date that defaults to the current date a time.

// Default
Epok()

// With Optional Offset date
Epok('6/29/2016') // or
Epok(new Date(6/29/2016))

now

Returns the current date

Epok().now

from

Used in conjunction with now or date to return a Date from the specified date/time

// Return the date 1 day from now
Epok().days(1).from.now

// Return the date 1 day from 6/29/2016
Epok().days(1).from.date('6/29/2016')

date

Used in conjunction with from to return a Date from the specified date/time

// Defaults to the current date if no date is specified
Epok().days(1).hours(4).from.date()

// You can use a string representation of the date
Epok().days(1).from.date('6/29/2016')

// Or you can pass a Date() object
Epok().days(1).hours(2).from.date(new Date('6/29/2016'))

ago

Returns the Date from some time ago

// Return the date 1 day ago
Epok().days(1).ago

// Return the date 1 day ago from 6/29/2016
Epok('6/29/2016').days(1).ago

to

Used in conjunction with milliseconds and seconds to return the duration in milliseconds or seconds. See milliseconds and seconds for usage.

milliseconds

Returns the specified duration in milliseconds

// Return 10 minutes in milliseconds
Epok().minutes(10).to.milliseconds

// Return 1 year, 2 days and 3 hours in milliseconds
Epok().years(1).days(2).hours(3).to.milliseconds

NOTE: Months cannot be converted to milliseconds currently because of the varying days in a month. This functionality is planned for the future.

seconds

Returns the specified duration in seconds

// Return 10 minutes in seconds
Epok().minutes(10).to.seconds

// Return 1 year, 2 days and 3 hours in seconds
Epok().years(1).days(2).hours(3).to.seconds

NOTE: Months cannot be converted to seconds currently because of the varying days in a month. This functionality is planned for the future.

minutes

Specify the number of minutes to be used in the duration or date calculation. minutes can be chained with other time functions. E.g. hours days weeks months years See example below

// Return the date 10 minutes from now
Epok().minutes(10).from.now

// Return 10 minutes in milliseconds
Epok().minutes(10).to.milliseconds

// Return the date 2 days, 3 hours, and 24 minutes from now
Epok().days(2).hours(3).minutes(24).from.now

hours

Specify the number of hours to be used in the duration or date calculation. hours can be chained with other time functions. E.g. minutes days weeks months years See example below

// Return the `Date` 10 hours from now
Epok().hours(10).from.now

// Return 10 hours in milliseconds
Epok().hours(10).to.milliseconds

// Return the `Date` 2 days, 3 hours, and 24 minutes from now
Epok().days(2).hours(3).minutes(24).from.now

days

Specify the number of days to be used in the duration or date calculation. days can be chained with other time functions. E.g. minutes hours weeks months years See example below

// Return the `Date` 10 days from now
Epok().days(10).from.now

// Return 10 days in milliseconds
Epok().days(10).to.milliseconds

// Return the `Date` 2 days, 3 hours, and 24 minutes from now
Epok().days(2).hours(3).minutes(24).from.now

weeks

Specify the number of weeks to be used in the duration or date calculation. weeks can be chained with other time functions. E.g. minutes hours days months years See example below

// Return the `Date` 10 weeks from now
Epok().weeks(10).from.now

// Return 10 weeks in milliseconds
Epok().weeks(10).to.milliseconds

// Return the `Date` 2 years, 3 months, and 22 weeks from now
Epok().years(2).months(3).weeks(10).from.now

months

Specify the number of months to be used in the duration or date calculation. months can be chained with other time functions. E.g. minutes hours days weeks years See example below

// Return the `Date` 10 months from now
Epok().months(10).from.now

// Return 10 months in milliseconds
Epok().months(10).to.milliseconds

// Return the `Date` 2 years, 3 months, and 22 weeks from now
Epok().years(2).months(3).weeks(10).from.now

years

Specify the number of years to be used in the duration or date calculation. years can be chained with other time functions. E.g. minutes hours days weeks years See example below

// Return the `Date` 10 years from now
Epok().years(10).from.now

// Return 10 years in milliseconds
Epok().years(10).to.milliseconds

// Return the `Date` 2 years, 3 months, and 22 weeks from now
Epok().years(2).months(3).weeks(10).from.now

isLeapYear([year])

Takes a year and returns true if it is a leap year and false otherwise

// true
Epok().isLeapYear(2000)

// false
Epok().isLeapYear(2015)

// true
Epok().isLeapYear(2016)
