- 8The .addDays() method does not work for dates that cross daylight saving time boundaries.mskfisher– mskfisher2013-04-29 00:02:16 +00:00Commented Apr 29, 2013 at 0:02
- 2This is one of the better answers here because you (correctly) use the number of millis since the epoc to represent dates/times, and add amounts of millis for adjustments... Why then did you not keep this up for "addMonths"!? And why no add year? Did you get bored?Robin– Robin2015-04-23 13:03:40 +00:00Commented Apr 23, 2015 at 13:03
- Other than months, time periods can be represented by static numbers. But months can be four different lengths. Also, any time period length from Days and higher may have variable length at DST, so you can't use time-based addition anymore without another level of complexity. I added the addYears(), and I fixed addMonths().Suamere– Suamere2016-04-16 19:55:34 +00:00Commented Apr 16, 2016 at 19:55

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
