Day 100 of the year
In a normal year, day 100 of the calendar is April 10 (April 9 in a leap year). By then the first quarter is over and about 27% of the year has gone. That is why spring is when many people review their New Year’s resolutions.
A 100-day plan is a good length for a personal project: long enough to build a skill, short enough to stay focused. Split it into 10 blocks of 10 days, with a short review at the end of each block.
In working time, 100 calendar days is about 71 or 72 working days before holidays, just over three months of full-time work.
