I live in the UK and in the US, presidential elections are scheduled to be held on the first Tuesday following the first Monday in November every fourth year, however it would be more plausible for the elections to be held on the first Tuesday (which is traditional in the US from an 1845 law) following any given month if a so that "snap elections" and "snap presidential races" can be held over there too like in the UK if needed, with the timing of the following election automatically reset after any "snap" election.

As an example, if a "snap" presidential election was held on Tuesday 6th August, 2024, the following timed election would also be exactly four years later unless a "snap" election was called, with the scheduled inauguration on 20th October. This is my proposed new system for the US.

The current outdated system lacks flexibility and in a democracy, if a snap election needs to be called, nobody should have to wait out the full length of a fixed four-year presidential term.
