My seed orders started arriving in late January. I always mark the year on the packets and then file them in a container that is the same width as the packet so they stand upright.
I use a divider between the vegetable varieties that lists all the germination requirements for starting seeds indoors. The information on the divider includes optimum temperature for the seed starting mix, days to germination, air temperature, planting depth, moisture and in some cases the light requirement. I also add the years of seed viability. Vegetable seeds can be viable up to 4-5 years.
The system I use to file the flower seeds is simpler. Seed packets offer a wealth of information. Most importantly for indoor seed starting is the estimated germination weeks so that you don't get way ahead of yourself. I use four dividers:
March 15-30 (approx. 10-12 weeks before planting out to the garden)
April 1-15 (approx. 8-10 weeks)
April 16-30 (approx.6-8 weeks)
May 1-15 (approx. 4-6 weeks)
Neither of my filing systems are foolproof but they offer guidelines and help keep me from starting short germinating zinnias or cucumbers indoors on March 15th.
Published vegetable seed viability charts are easily available on the internet but charts for flower seeds are harder to find. Look on-line using the search - seed viability charts, edu sites only. Adding the edu sites only should bring up educational sites only. [

If you do have seeds that have been around since you don't remember when, you might want to test for germination rather than waste time and resources on seeds that aren't viable. That is why it is a good idea to mark the year on the front of the packet, unless you intend to plant the entire contents in that season.

I have some packets that have been neglected for far too long and they will get the paper towel treatment this year.
