Exercise

Generating sequences of datetimes

By combining addition and multiplication with sequences you can generate sequences of datetimes. For example, you can generate a sequence of periods from 1 day up to 10 days with,

1:10 * days(1)

Then by adding this sequence to a specific datetime, you can construct a sequence of datetimes from 1 day up to 10 days into the future

today() + 1:10 * days(1)

You had a meeting this morning at 8am and you'd like to have that meeting at the same time and day every two weeks for a year. Generate the meeting times in this exercise.
