Which schedule is better for me?

The total is identical, so the question is about matching your outgoings. Rent, loan instalments and subscriptions almost all fall monthly, which makes monthly or twice-monthly pay the tidier fit: the money and the bills use the same calendar. Fortnightly pay drifts against that calendar all year and needs a buffer of roughly one cheque to absorb the drift, in exchange for arriving more often and shortening the gap you have to bridge if something goes wrong. Weekly pay smooths that further still. None of these is superior in cash terms and none should sway a decision between two jobs.

Why isn't a fortnight a month divided by two?

Because a year holds 26 fortnights and only 24 half-months. Twelve months average about 30.4 days each, so half a month averages 15.2 days while a fortnight is exactly 14 — a gap of over a day per period, which accumulates into two whole extra pay dates by the end of the year. The same mismatch is why a fortnightly schedule cannot be tied to fixed dates and always drifts across weekdays and month boundaries, and why some years contain 27 fortnightly pay dates instead of 26 depending on where the first one falls.

Biweekly and Semi-Monthly Pay Are Not the Same Thing

In short

A yearly salary can be sliced four common ways and the slices are not interchangeable. $52,000 gives $1,000 a week over 52 pay dates, $2,000 a fortnight over 26, $2,166.67 twice a month over 24, and $4,333.33 monthly over 12. The fortnightly and twice-monthly figures are the pair that causes trouble, because both are loosely called "every two weeks" and the second is 8.33 per cent larger per cheque. Neither pays more over a year. The practical consequence is on the calendar rather than the total: twice-monthly pay always lands two cheques in a month, while fortnightly pay lands three in two months of the year, and a budget built on "two cheques cover the month" quietly leaves 7.7 per cent of annual pay unallocated.

On $52,000 a year, a fortnightly cheque is $2,000 and a twice-monthly one is $2,166.67. The second looks 8.33 % better and pays exactly the same — because there are 26 of the first and 24 of the second.

The third-cheque months are not a bonus

Twelve months of two fortnightly cheques comes to 24 payments and $48,000, which is $4,000 short of the salary. The missing money arrives as the 25th and 26th cheques, in whichever two months the calendar happens to put them, and it is not extra income — it is the 7.7 per cent that the monthly arithmetic quietly dropped. Treating those months as windfalls and the other ten as normal produces a budget that is permanently tight and occasionally flush. The fix is to divide the annual figure by twelve for planning and let the pay calendar do whatever it does.

Everything here is gross

The division says nothing about what reaches the account. Income tax, social contributions, pension deductions and any benefit levies come out afterwards, at rates that depend on the country, the household and often on the pay period itself — a progressive withholding table applied 26 times is not identical to the same table applied 24 times, and reconciliations at year end exist precisely because of that. Use this figure to plan a salary negotiation, to compare two offers quoted at different frequencies, or to sanity-check a payslip's gross line, and use a country-specific net calculator for what actually lands.
