In some countries, the band starts at 432 MHz. In the UK, repeaters are around 433MHz, and the band is only 430-440MHz. (And in some countries, there is no allocation at all.) The 2m band is sometimes referred to as the 144MHz band, and the 3rd harmonic of that is 432MHz. I have heard the 23cm band referred to as the 1296MHz band, too - for the same reason (3rd harmonic of 432MHz and 9th harmonic of 144MHz).
