It is important to note that if we construct a date using the new Date(year, month, day) constructor, the parameters use your local timezone. We must decrement the day parameter by 1. Which we know is off by 1 day because of the leap year issue mentioned above. The easiest way to work this out, IMHO, is to consider all Excel dates entered as UTC (if you can). Excel doesn't have a concept of a timezone in its date representation, but JS does. Now, how do we represent ? To easier view the output in terms of a date I like to do new Date(Date.UTC(1970, 0, 1, 0, 0, 0, 0)).toISOString() gives 'T00:00:00.000Z' Here, we decrement the day from 0 to 1, and increase the hours, minutes, seconds and milliseconds. It does accept numbers outside those ranges and converts the input to over or underflow the other parameters. It has some interesting functionality which we can use to our benefit.Īll normal ranges of the parameters of Date.UTC() are 0 based except day. If we use Date.UTC(year, month, ?day, ?hour, ?minutes, ?seconds) it will return the number of milliseconds since that base time, in UTC. is 367.0, +366 days (Excel incorrectly treats 1900 as a leap year)ĭates in JS are based on Jan 1st 1970 UTC. See Browsers, time zones, Chrome 67 Error (historic timezone changes) so I'd like to stay in UTC and not rely on any shifting of hours if at all possible.Įxcel dates are integers based on Jan 1st, 1900 ( on PC. Note: There could be issues with timezone offsets, especially for older dates (pre-1970). I really liked the answers by and and while they mostly work, I wanted to dig a bit deeper to understand how Date.UTC() worked.
