The leaders of the ten or twenty leading parties; err, the count had been lost; all solemnly promise that the pledges they make will be acted upon within the first hundred days of their being returned to power.
These pledges are firm promises that their relevant and incidental pledges will conform with the overall contextual promises on which the overarching pledges and promises are based.
I hope this statement makes the position clear.
As for the hundred days the definition of day will be dependent on which planet in our solar system is deemed most relevant, probably Venus.
However, the terms and conditions allow flexibility in determining the solar system which is applied to the issue in question.
I hope this assists with your forward planning.
