Apple has pushed back the date of its second-quarter earnings report by 24 hours, to April 26.

Previously, the conference call to discuss its results was scheduled for April 25 at 2 p.m. PT.

The change was announced on Apple's investor-relations page, which displayed the new date on Wednesday. Apple did not provide any explanation for the scheduling change.

CNBC reports that the reason the earnings were delayed is because of a memorial service for Bill Campbell, a longtime member of Apple's board, who died earlier this week.

It's not unheard of for earnings to be postponed, although most companies don't attract the same attention that Apple does. Some earnings are postponed because an internal audit took longer than expected or for other unforeseen reasons.

This quarter is an important one for Apple. Many investors are worried that iPhone sales, the company's economic engine, might be unusually slow this quarter. Nikkei reported last week that iPhone production will remain slow through June, which temporarily dropped Apple's stock price.

But other analysts remain bullish on Apple because of its opportunity in the online-services market, as well as the fact that it continues to capture the vast majority of profits in the smartphone market.

Apple representatives did not immediately return calls for comment.
