Re: ADO adDate Value Calculation

I am able to calculate the number of days since December 30, 1899,
but I don't know the formula for calculating the fraction of a day.

Use floating-point

1.0 represent a whole day and fractions are from midnight, the start of a
day.

So

0.0 is 00:00:00 on a 24-hour clock
0.25 is 06:00:00 on a 24-hour clock
0.5 is 12:00:00 on a 24-hour clock
0.75 is 18:00:00 on a 24-hour clock
0.125 is 03:00:00 on a 24-hour clock
0.1 is 02:24:00 on a 24-hour clock
0.01 is 00:14:24 on a 24-hour clock
etc.

86400 seconds in a day
