February is the only month whose length moves. In an ordinary year it runs to 28 days and in a leap year to 29, and 2030 gives it 28. The rule is older than it looks: a year divisible by four gains a day unless it is also divisible by 100 and not by 400, which is why 1900 was an ordinary year and 2000 was not.
Because nothing interrupts it, the working-day total for February 2030 depends purely on how its 28 days fall against the weekends. That makes it the most predictable month of the year for rostering, project planning and anything scheduled in five-day blocks — and the one where a leap day quietly adds an extra day of pay to a monthly-paid workforce.
The move from February into March brings meteorological spring on the 1st, St David's Day on the same date, and a month that carries both the equinox and the start of British Summer Time. February 2030 hands over the last genuinely wintry weeks to the month where the season visibly turns.
