Can anyone help.

I have a known start date of 1/1/2000 @ 00:00 and I have information that tells me the number of minutes since that day is 6509435 for a particular ocuurance, how can I find out th exact date and time that the 6509435 minute occured taking into account leap years etc.

I know that 6509435 minutes / 60 is 108490.58 hours which is 4520.44 days which is approx 12.38 years, but i am looking for the exact date & time.
that 6509435 minutes was since 1/1/2000 @ 00@00
Many thanks

Basic formula would be

=A1+(B1/1440)

Where A1 holds the start date and time, B1 holds the number of minutes to add.

Format the results as dd/mm/yyyy hh:mm:ss or similar as required.

Excellent, may thanks for your help.
