Valentine's Day on the 14th and, in most years, Shrove Tuesday give February 2029 its two fixed points. Snowdrops come through in the first half of the month and the earliest crocuses follow, the Six Nations is under way, and the coldest temperature of the whole winter is recorded in February more often than in any other month.
February sits in the middle of the first calendar quarter and in the eleventh month of the tax year, with the 5 April cut-off now close enough to matter. Pension contributions, ISA allowances and anything else measured against the tax year rather than the calendar year start appearing on people's lists during February 2029 rather than in the panic of late March.
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 2029 hands over the last genuinely wintry weeks to the month where the season visibly turns.
