All the books that I am importing since the latest update to 2.8 have a published date of Jan 0101. How do I correct this. I am going into each book and changing the date, but how do I get it to stop doing this.

Running a Mac with Yosemite.

That date is supposed to equal 'Un defined' (no date) and not show. Does any of your Metadata source choices supply 'Published' ? If you have only a single source, that may be broken due to a site change (hint: tell us the name

)

If that is not the problem:

The same i have with the publishing Date. By the date i get when i push the green button (delete date) 02 jan. 0101 and by the publishing date i get jan. 0101 when i push the green button (delete date). My source is the Bol.com plugin.

This issue is reported fixed in post #2 above and the fix will be in the next release.

I have now version 2.9 but there is one problem left. When i use the Bol.com plugin and I go to that site i use always the isbn number. Then i run Calibre to search in Bol.com. He get the information but i see a different publishing date. One month different between what Bol.com had on there site and what Calibre fills in. On the Bol.com site there is standing March 2013 but i get Februari 2013 in Calibre. PrBarnart who made the plugin doesn`t know why there is an one month different publishing date.

It will be a timezone issue, in some timezones the 1st of a month will be the last day of the previous month. Tell him to use the calibre.utils.date.parse_only_date function or to manually set the day of the date to 2nd instead of first. Or set the timezne info on the date to the local timezone.

Ok Thanks i will tell him

Just upgraded to 2.9 and still can't change the Published date manually. I'm trying to type just a year, say 1953, and nothing happens. Any hints?

I'm running on Windows 7 Ultimate 32 bits.

@tromaster - see Preferences->Tweaks->Control how dates are displayed also controls how they are entered.

To clear a date enter '-' (minus) to make a date today enter '=' (equals)

Hi,
Setting the day to 2nd , as default, is a workaround.
What did change in calibre for this issue,because version 2.6 gave no problems with this at all.
I was used to create the date by:

Code:

 from calibre.utils.date import utc_tz
        return datetime.datetime(year, month, day, tzinfo=utc_tz)

I thought this way there is no timezone issue.

Thanks for the tip, BR, that worked fine.

The date is displayed in the local timezone, if you set to to the a particular day in the UTC timezone, that might be the previous day in the local timezone. Either use the second or use local timezone.
