Formula Used:

TIC12 = 1 / (mhz / 12)TIC6 = 1 / (mhz / 6)
8-bit Timer Counter Maximum Run-Time for 12 clock = TIC12 * 256 / 1000
8-bit Timer Counter Maximum Run-Time for 6 clock = TIC6 * 256 / 1000
16-bit Timer Counter Maximum Run-Time for 12 clock = TIC12 * 65536 / 1000
16-bit Timer Counter Maximum Run-Time for 6 clock = TIC6 * 65536 / 1000
8-Bit DRT Reload Value for 12 clock = 256 -(DRT / TIC12 * 1000)
8-Bit DRT Reload Value for 6 clock = 256 -(DRT / TIC6 * 1000)
16-Bit DRT Reload Value for 12 clock = 65536 -(DRT / TIC12 * 1000)
16-Bit DRT Reload Value for 6 clock = 65536 -(DRT / TIC6 * 1000)

Calculation of 8051 uc time delay is made easier using this online electronics calculator.
