Google Sheet Script - 日期差异 - 当前日期（） - 电子表格中的日期（）

Question

I`m trying to calculate dates in my data - NOW() (Current Date) in days

So

Dates           Today              Days difference

2019-01-01     2019-03-11            X
2019-02-01     2019-03-11            X 

and I would like that Today to be updated everyday

Is there way to do this in Script so that "Days difference" can be updated daily automatically?

Also is it possible to highlight any rows with red that are greater than 100 days?

Answer 1

Googlescripts seem to use dates that are basically the same as javascript dates, so you should be able to do something like this:

 var dateFromFirstColumn = new Date("2019-01-01"); var now = new Date(); var today = new Date( now.getFullYear(), now.getMonth(), now.getDate(), 0,0,0); // Midnight last night, since presumably the first date is similar var todayString = today.toLocaleString(); // Can be written to second column var diff = today.getTime() - dateFromFirstColumn.getTime(); var millisecondsInADay = 1000 * 60 * 60 * 24; var diffInDays = Math.floor(diff/millisecondsInADay); console.log(diffInDays);

I can't say for sure that googlescripts supports Math.floor() and the like, but this should get you close.

Assuming the automatic formatting of .toLocaleString isn't what you want, you can use the .getFullYear , .getMonth , and .getDate methods (and pad any single-digit days with a leading zero), then concatenate the results into the YYYY-MM-DD format. (Note that January is month number zero when converting month numbers to text.)
