So I have a Javascript date object with year, month, days, hours, minutes, seconds, and milliseconds data and I need to convert this object to an Excel serial number but I didn't find a way to do that. I found how to convert only a Date object but the way I found didn't consider the time part.
Any suggestions? Thank you, Regards.
finally I was able to convert it properly, I used the following code to do so:
let date = new Date();
let converted = 25569.0 + ((date.getTime() - (date.getTimezoneOffset() * 60 * 1000)) / (1000 * 60 * 60 * 24));
Thank you all.
Try this:
function ExcelDateToJSDate(serial) {
var utc_days = Math.floor(serial - 25569);
var utc_value = utc_days * 86400;
var date_info = new Date(utc_value * 1000);
var fractional_day = serial - Math.floor(serial) + 0.0000001;
var total_seconds = Math.floor(86400 * fractional_day);
var seconds = total_seconds % 60;
total_seconds -= seconds;
var hours = Math.floor(total_seconds / (60 * 60));
var minutes = Math.floor(total_seconds / 60) % 60;
return new Date(date_info.getFullYear(), date_info.getMonth(), date_info.getDate(), hours, minutes, seconds);
}
Or you can use:
function SerialDateToJSDate(serialDate) {
var days = Math.floor(serialDate);
var hours = Math.floor((serialDate % 1) * 24);
var minutes = Math.floor((((serialDate % 1) * 24) - hours) * 60)
return new Date(Date.UTC(0, 0, serialDate, hours-17, minutes));
}
