When to move
Next move: Fri, Feb 12, 2027. Move to G Fund (10th trading day of February). The cutoff is 12:00 noon Eastern Time on a business day; a request in before it gets that day's share price.
Holding now: S Fund, since Oct 15, 2026.

Add these dates to your calendar (a calendar file with a reminder the evening before and one on the morning of each move).
Dates after Oct 27, 2026 are the expected business days: weekdays that are not stock-market holidays, Columbus Day or Veterans Day, from the holiday calendar checked through Dec 31, 2027. An unplanned market closure pushes a move to the next business day. How transfers post.
