## Usage ```javascript var SECONDS_IN_WEEK = require( '@stdlib/constants/time/seconds-in-week' ); ``` #### SECONDS_IN_WEEK Number of seconds in a week. ```javascript var bool = ( SECONDS_IN_WEEK === 604800 ); // returns true ```
## Notes - The value is a generalization and does **not** take into account inaccuracies due to daylight savings conventions, crossing timezones, or other complications with time and dates.
## Examples ```javascript var randu = require( '@stdlib/random/base/randu' ); var roundn = require( '@stdlib/math/base/special/roundn' ); var SECONDS_IN_WEEK = require( '@stdlib/constants/time/seconds-in-week' ); var secs; var wks; var i; function wks2secs( wks ) { return wks * SECONDS_IN_WEEK; } for ( i = 0; i < 10; i++ ) { wks = roundn( randu()*20.0, -2 ); secs = wks2secs( wks ); console.log( '%d weeks => %d seconds', wks, secs ); } ```
