I often go on business trips, for which I find myself always add the same tasks: Book the flight and hotel (timed three weeks in advance), pack (timed on the day before) and file an expense report (timed on the day after the event).

I wrote a little shell script (based on rumember, https://github.com/tpope/rumember) that automates this. It calculates the relative dates and makes a list of tasks, in relative timing to the "main" thing. It can surely be adjusted to suit your needs in terms of timed tasks that often occur together:


--- trip --

#!/bin/bash

if [ -z "$2" ]
then
echo ""
echo "Syntax: trip TITLE 31.05.2015"
else


day=`date -jf '%d.%m.%Y' $2 '+%d.%m.%Y'`

day_after=`date -v+1d -ujf"%d.%m.%Y" $day +%d.%m.%Y`;
day_before=`date -v-1d -ujf"%d.%m.%Y" $day +%d.%m.%Y`;
threeweeks_before=`date -v-21d -ujf"%d.%m.%Y" $day +%d.%m.%Y`;
