Some Social Security recipients could face a unique set of checks starting next month, and it's all thanks to an interesting quirk in the 2024 and 2025 calendars.

The first change will come in November, when recipients will be sent two checks instead of the usual check.

Typically, Supplemental Security Income recipients receive their checks on the first of each month, but in November a second check also arrives at the end of the month.

This is due to a rule that if the first of the month falls on a holiday or weekend, checks will be delivered on the previous day of the week.

In December, the first of the month falls on a Sunday, meaning checks for the month of December will be delivered on November 29 instead, according to the Social Security Administration calendar.

However, that does not mean that there will be no controls in December.

A similar calendar feature actually affects check delivery for each month through March, with the beginning of each month falling on either a holiday or a weekend.

For January, checks will actually be delivered on December 31st. For February checks will be delivered on January 31st and for March checks will be delivered on February 28th.

Checks will no longer be delivered in March before normality returns in April.

That's not the only change coming to welfare recipients.

The Social Security Administration announced Oct. 10 that millions of retired Americans will soon see a 2.5% cost-of-living adjustment in benefit payments. At the same time, the agency announced a higher threshold for earnings subject to the Social Security payroll tax, called the “taxable maximum” or “wage base,” according to CNBC.
