How many Mondays until Earth Day?

How the count is worked out
Counting starts from tomorrow, not today, and includes Earth Day itself if it lands on a Monday. That matters most when the event is close: a difference of one day at the start can change the total by a whole Monday. Because weekdays repeat every seven days, the count is roughly the number of days remaining divided by seven, then rounded up or down depending on which weekday today is. Today is a Tuesday, and Earth Day falls on a Thursday.
Mondays until Earth Day in future years
The figure changes every year, because both the starting date and the weekday Earth Day falls on shift. Counted from the same point each year:
| Earth Day | Weekday | Mondays in the year before |
|---|---|---|
| April 22, 2027 | Thursday | 52 |
| April 22, 2028 | Saturday | 52 |
| April 22, 2029 | Sunday | 52 |
| April 22, 2030 | Monday | 53 |
| April 22, 2031 | Tuesday | 52 |
Mondays by month
How the remaining mondays spread across the calendar between now and Earth Day:
| Month | Mondays |
|---|---|
| September 2026 | 1 |
| October 2026 | 4 |
| November 2026 | 5 |
| December 2026 | 4 |
| January 2027 | 4 |
| February 2027 | 4 |
| March 2027 | 5 |
| April 2027 | 3 |
Most months contain four of any given weekday, and some contain five. A month has five of a weekday whenever its length runs past the fourth occurrence, which is why the totals above are not evenly spread.
