No fixed national public holiday falls in February. School Term 1 is in full session in every state by 16 February 2030, and the 28 days of February in 2030 run as an unbroken stretch of ordinary working and school days unless a state has declared a separate regional holiday of its own for a local event or observance.
A public holiday that falls on a Saturday sits inside the weekend rather than beside it, so it does not automatically create a substitute day off during the working week; whether one applies depends on the specific holiday and the state. Saturday 16 February 2030 falls on this day of the week, inside the weekend itself.
The week number shown for 16 February 2030 counts full weeks from the start of 2030, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
