Beware of possible ambiguity when using this with days of the week. This Tuesday will usually be taken to mean 'the Tuesday of this week', but if the time of speaking is midway between two Tuesdays, this Tuesday might refer to the one passed or the one to come. The same is true of next and last. If said on a Sunday, next Tuesday might be the day after tomorrow or the Tuesday of the following week; on a Thursday, last Tuesday could be the day before yesterday or the Tuesday of the previous week. Avoid using these terms in writing, as you do not know when it may be read; give the date.
Red, white, and blue recall the French tricolour. Red, yellow, and green are the pan-African colours. Red represents the common blood of mankind which links African and European nations. Effective date: 1 December 1958.
