For reasons long forgotten and now covered by the essentially meaningless blanket explanation of "tradition", Budgets are always delivered on a Thursday afternoon.
One should be grateful for small mercies. In the good old days, the Minster of Finance did not start reading the lengthy Budget speech until MPs had returned to the House at 7.30pm following the dinner break.
If some appeared to have devoted much of that intermission to taking advantage of the cut-rate liquor prices that used to apply in the bars and restaurants, that was understandable.
Ahead of those MPs was more than likely an all-night sitting to pass legislation okaying a rise in the price of booze and fags for everyone else.
A revamp of Parliament's rules in 1995 shifted the delivery time back to 2pm. It would have made more sense to present the document at 2pm on a Tuesday afternoon when the House begins its sitting week.
