For many years, BHP Group Ltd (ASX: BHP) was the largest share on the Australian stock markets, only relatively recently being deposed by Commonwealth Bank of Australia (ASX: CBA).

Despite this, the 'Big Australian' remains one of the largest mining companies in the world and is a staple investment in Australian share portfolios, regardless of age. Investors can't seem to get enough (understandably so) of the diversified, low-cost exposure to minerals like iron ore, potash, nickel and copper that BHP can lend to a portfolio.

As such, it goes without saying that the BHP financial calendar is an important document for many ASX investors. So today, let's go over some of the major dates that anyone with ownership or interest in BHP shares will want to circle on their calendars this year. 

What to expect from the Big Australian in 2025

According to BHP's official 2025 shareholder calendar, the first event that investors might want to pay attention to this year is the 'operational review' scheduled for later this month on the morning of 21 January.

These operational reviews are typically when BHP provides a quarterly update to investors, including production and sales updates. As such, this month's report will give investors their first financial update from the miner since October last year. This might well set the tone for BHP's entire 2025.

Next on the calendar, we have BHP's half-year earnings report, which will drop on the morning of 18 February. This is another big occasion for shareholders. They will receive the full report for BHP's revenues, earnings and profits for the six months to 31 December 2024.

Crucially, shareholders will also find out exactly how much BHP's first dividend payment for 2025 will be worth.

Following these earnings, BHP will deliver another quarterly operational review on 17 April, this one covering the nine months to 31 March 2025.

Rather unusually for a blue-chip ASX 200 share, BHP has not yet given us any dates on its financial calendar that come after 17 April. So we might have to wait a while until we learn when the miner's full-year results will be released, or when its annual general meeting (AGM) will be held. For a guide, these events occurred on 27 August and 30 October respectively in 2024.

In contrast to the broader stock market, BHP shares had a horrible 2024. The miner dropped from $50.41 a share at the start of the year to $39.55 by the end. That's a fall worth 21.54%.
